Background and objectives: Prolactin is a lactogenic protein hormone secreted by the anterior pituitary that initiates and maintains lactation in mammals. Previous research has linked increased serum prolactin levels to breast cancer. However, there is a paucity of studies in the Indian population on the subject. The present study evaluated and compared serum prolactin levels in patients with breast cancer and patients with benign breast diseases.
Methods: This cross-sectional, comparative study was carried out at the Government Medical College, Nagpur (India) on patients with breast diseases in the out-patient department/in-patient department from June 2018 to November 2020. Breast cancer patients were considered cases, and those with benign breast diseases were considered controls. Breast carcinoma diagnosis was based on clinical features, fine needle aspiration cytology, and tissue histopathology in operated specimens for each patient. Fasting serum prolactin levels were measured by the chemiluminescence immunoassay method using the Advia Centaur immunoassay system.
Results: There were 120 female patients with breast diseases, of whom 60 had breast malignancy, and 60 had benign breast diseases. The mean age of patients with benign breast disease and breast cancer was 33.17 (1.75) and 49.77 (1.16) years, respectively (P<0.0005). Increased serum prolactin levels were observed in 93.3% of patients with breast cancer and 13.3% of patients with benign breast diseases. The mean serum prolactin level was significantly higher among breast cancer patients (102.68±7.03) ng/ml compared with patients with benign breast disease (16.31±1.72 ng/ml). We successfully determined a new cut-off value of serum prolactin level (>40.2 ng/ml) to differentiate breast cancer from benign breast diseases using the receiver operating characteristic curve analysis.
Conclusion: Patients with breast cancer have increased serum prolactin levels compared to patients with benign breast diseases. Thus, serum prolactin level can be used as a diagnostic marker for breast cancer. This is particularly beneficial to clinicians for differentiating breast cancer from benign breast diseases.

Background and objectives: Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease caused by the accumulation of large amounts of fat in the hepatocytes. Given that atorvastatin is effective for treatment of NAFLD, the present study investigated effects of high-fat/fructose diet (HFFD) with atorvastatin on liver enzymes and lipid profile in a NAFLD rat model.
Methods: Thirty-two male Wistar rats were divided into four groups: 1) normal control, 2) HFFD control, 3) HFFD + atorvastatin, and 4) normal + atorvastatin. The groups received HFFD for 15 weeks to induce hepatosteatosis. Atorvastatin was administrated at the dose of 10 mg/kg/day. Lipid profile and liver enzymes were measured after eight weeks of intervention.
Results: Triglyceride, cholesterol, gamma-glutamyl transferase, and aspartate transaminase were significantly reduced in the HFFD + atorvastatin group compared with the HFFD control group. In addition, cholesterol, high-density lipoprotein, alkaline phosphatase, and gamma-glutamyl transferase were significantly increased in the normal + atorvastatin group compared with the normal control group. Low-density lipoprotein increased significantly in the HFFD + atorvastatin group and the normal + atorvastatin group compared with other groups. There was a significant difference in the alanine transaminase levels between the groups taking atorvastatin. In fact, alanine transaminase level was lowest in the normal + atorvastatin group.
Conclusion: Atorvastatin improves the lipid profile and fatty liver and controls liver enzymes. Therefore, it can be used with caution to improve the lipid profile and reduce the complications of NAFLD.

The prevalence of hypothyroidism is much higher among women than in men. Hypothyroidism is also one of the most prevalent thyroid disorders among women of reproductive age. The disease exerts its effect on female sex hormones by manipulating the production of luteinizing hormone and follicle-stimulating hormone that are crucial for the production of estrogen by the ovaries. Various studies demonstrated the adverse effect of overt hypothyroidism on ovulation, menstrual cycle, and fertility. This review surveys the adverse effects of hypothyroidism on fertility and pregnancy.

Background and objectives: Piper guineense (African black pepper) is a widely consumed spice in some parts of Central and Western Africa, especially Nigeria, due to its nutritional and medicinal properties. This study investigated biochemical effects of extract of P. guineense seeds on lipid profile, renal function parameters, and antioxidant status of Cavia porcellus.
Methods: Forty guinea pigs (weighing 200–300g) were equally divided into a control group and three experimental groups. Animals in the control group received 1 mL of distilled water daily for 28 days, while animals in the experimental groups 1, 2, and 3 received 0.5 mL of distilled water along with 10, 20, and 20 mg/100 g body weight powered seeds daily for 28 days.
Results: Phytochemical studies revealed the presence of flavonoids, alkaloids, tannins, saponins, and calcium. The median lethal oral dose of the aqueous extract of P. guineense seeds was greater than 5,000 mg/kg, indicating a high degree of safety. The extract at dose of 30 mg/100 g body weight had the most beneficial effects on lipid profile, renal function parameters, and antioxidant status of guinea pigs when compared with other groups.
Conclusion: Given the beneficial effects of P. guineense on lipid profile and renal function parameters, the plant can be incorporated in daily diets to ensure receiving adequate amount of essential vitamins, phytochemicals, and other nutrients present in the plant.

Background and objectives: Activation of adenosine A2a receptor has been shown to induce the growth and metastasis of cancer cells. The role of this receptor in esophageal cancer has not yet been determined. The present study aimed to investigate effects of an adenosine A2a receptor antagonist (3, 7-dimethyl-1-propargylxanthine) on growth of esophageal cancer cells.
Methods: Real-time polymerase chain reaction was performed to evaluate mRNA expression of the A2a adenosine receptor in KYSE-30 and YM-1 esophageal cancer cell lines. Effects of the antagonist on viability of the cells were evaluated by MTT assay.
Results: At low concentrations, the antagonist had no effect on cell viability. However, at concentrations ≥200 μM, the antagonist significantly reduced viability of both cell lines (p<0.05).
Conclusion: The results of this study indicate that the adenosine A2a receptor antagonist exerts inhibitory effects on KYSE30 and YM-1 cancer cells in a dose-dependent manner. Therefore, the use of this antagonist can be exploited as a therapeutic target for the treatment of esophageal cancer.

Background and objectives: The outbreak of coronavirus disease 2019 (COVID-19) has become a global health emergency. The severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) NSP13 helicase plays an important role in SARS-CoV-2 replication and could serve as a target for the development of antivirals. The objective of the study was to perform homology modeling and docking analysis of SARS-CoV-2 NSP13 helicase as a drug target.

Methods: The structure and function of SARS-CoV-2 NSP13 helicase were predicted by in-silico modeling studies. The SWISS-MODEL structure assessment tool was used for homology modeling and visual analysis of the crystal structure of the protein. The validation for structure models was performed using PROCHECK. Model quality was estimated based on the QMEAN and ProSA. The MCULE-1-Click docking and InterEvDock-2.0 server were used for protein-ligand docking.
Results: The SARS-CoV-2 NSP13 helicase model corresponded to probability confirmation with 90.9% residue of the core section, which highlights the accuracy of the predicted model. ProSA Z-score of -9.17 indicated the good quality of the model. Inhibitor N-(3-(carbamoylamino) phenyl) acetamide exhibited effective binding affinity against the NSP13 helicase. The docking results revealed that Lys-146, Leu-147, Ile-151, Tyr-185, Lys-195, Tyr-224, Val-226, Leu-227, Ser-229 residues exhibit good binding interactions with inhibitor ligand N-(3-(carbamoyl amino) phenyl) acetamide.
Conclusion: Hence, the proposed inhibitor could potently inhibit SARS-CoV-2 NSP13 helicase, which is thought to play key roles during viral replication. The results of this study indicate that N-(3-(carbamoylamino) phenyl) acetamide could be a valuable lead molecule with great potential for SARS-CoV-2 NSP13 helicase inhibition.

Background and objectives: Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) inhibition results in an increase in apoptosis. It has been demonstrated that NF-κB subunit p65 phosphorylation at the IκB kinase phosphorylation site serine 536 (Ser536) is essential for the NF-κB nuclear translocation and activation. Therefore, NF-κB can be downregulated by suppressing its phosphorylation. The vascular endothelial growth factor receptor-2 (VEGFR-2) suppression could result in apoptosis induction. Therefore, targeting these pathways via VEGFR-2 inhibitors might have therapeutic potential for cancer treatment. It has been indicated that an antagonist peptide of VEGF, referred to as VGB3, could neutralize and recognize VEGFR2 in the tumoral and endothelial cells. This study aimed to induce apoptosis in human umbilical vein endothelial cells (HUVEC) cells through the inhibition of these signaling pathways.
Methods: Effects of different concentrations of VGB3 (1-200 ng/ml) were evaluated on the viability of HUVEC  cells using MTT assay. In addition, downstream signaling pathways in HUVE cells were evaluated through quantitative assessment of protein expression via western blotting.
Results: The results demonstrated that VGB3 treatment inhibited the growth of HUVEC cells. Moreover, Bcl-2 was decreased in the cells treated with the VGB3 compared to the control. Furthermore, VGB3 significantly enhanced the cleaved-caspase7 levels, which is an indicator of apoptosis progression. Altogether, VGB3 enhanced apoptosis in HUVEC cells.
Conclusion: Our results indicate that the peptide might be a potential candidate for antitumor therapy via inhibiting the NF-κB pathway.

Background and objectives: Genetic studies have indicated the effective role of transcription factors in insulin synthesis and secretion, especially in the case of diabetes. This study aimed to assess the effects of high-intensity interval training on transcription factor 7-like 2/ glucagon-like peptide 1 (TCF7L2 / GLP-1) axis in pancreatic tissue of obese rats with type 2 diabetes mellitus (T2DM).
Methods: For this purpose, obesity was induced in 21 male Wistar rats (weighting 220±10 g) by exposure to a high-fat diet for six weeks. Then, the rats were randomly assigned to a non-diabetic, a control T2DM, and an exercise diabetic group. Next, T2DM was induced by intraperitoneal injection of streptozotocin (25 mg/kg). The rats in the exercise group participated in a HIIT program, five times a week, for six weeks. After the intervention, TCF7L2 and GLP1 expression in the pancreas tissue was determined by real-time PCR. Serum insulin, glucose, and beta cell function were compared between the study groups. Data were analyzed using one-way ANOVA and Tukey post hoc test at a significance level of 0.05.
Results: Induction of T2DM increased glucose level and TCF7L2 expression but decreased insulin, beta cell function, and GLP-1R expression. In addition, HIIT significantly decreased TCF7L2 expression as well as glucose level, serum insulin, and beta cell function; however, it did not significantly change GLP-1R expression compared with the control diabetes rats.
Conclusion: Based on the findings, the improvement of serum insulin and glucose level following HIIT may be attributed to the decrease in TCF7L2 gene expression in the pancreatic tissue of diabetic rats.

Background: Multiple sclerosis (MS) is a demyelination disorder of the central nervous system (CNS), which is believed to be associated with oxidative stress. Therefore, researchers try to find reliable biomarkers to monitor the disease and predict its prognosis. Cholesterol and lipids in the myelin sheath are vital for nerve cells. Serum low-density lipoprotein (LDL) is susceptible to lipid peroxidation induced by oxidative stress. This study aimed to evaluate oxidative stress markers in the serum of patients with relapsing-remitting MS (RRMS) and examine their correlation with lipid markers.
Methods: A total of 18 MS patients (14 women and 4 men) and 18 healthy subjects (matched by age and sex) were enrolled in this cross-sectional study. The serum samples were collected in both relapsing and remitting phases. The prooxidant-antioxidant balance (PAB), malondialdehyde (MDA), and oxidized LDL (oxLDL) were measured as markers of oxidative stress.
Results: The mean age of participants was 29.21 (22-42) years. In the comparison between the patient and control groups, the most differences were increased levels of PAB in the patient group (P < 0.05), no difference between relapsing and remitting phases (P = 0.995), increased MDA levels in the relapsing phase (P = 0.013)––but no change in the remitting phase (P = 0.068), no difference in LDL and oxLDL levels in the patient group (P > 0.05), and MDA, LDL, and oxLDL levels did not have any significant correlation with PAB (P > 0.05).
Conclusion: High levels of oxidative stress markers were present in both phases of the disease. Lipid peroxidation markers (such as MDA) increased in the acute phase, but oxLDL did not change. Also, there was no significant correlation between oxidative stress and cholesterol markers.

Background: Research has shown that the extract of some plants has an effective protective effect on liver cells against toxins and oxidants. In this research, the effect of hydroalcoholic extract of ginger against hepatotoxicity caused by doxorubicin (Dox) in adult male rats was investigated.
Methods: In this experimental study, 63 adult male rats were divided into 7 groups (n = 9 per group). The experimental treatments included the control and placebo groups without the use of medicines, experimental group I that received Dox at a dose of 20 mg/kg, experimental groups II and III with 300 and 600 mg/kg of ginger hydroalcoholic extract, and experimental groups IV and V that received 20 mg/kg Dox + 300 and 600 mg/kg of ginger hydroalcoholic extract, respectively. After the end of the test period, serum levels of total bilirubin and direct bilirubin were measured. In addition, the histological changes in the liver were examined after hematoxylin and eosin (H&E) staining.
Results: Serum levels of total bilirubin and direct bilirubin in the Dox group showed a significant increase compared to the control group. In contrast, serum levels of total bilirubin and direct bilirubin in Dox + ZIN 600 and Dox + ZIN 300  had a significant reduction compared to the Dox group (P < 0.05). Ginger extract prevented apoptosis and Dox-induced liver tissue damage in dose-dependent designs.
Conclusion: The hydroalcoholic extract of ginger improves the changes of serum bilirubin and liver tissue after receiving Dox due to its antioxidant compounds.

Background: Aflatoxin B1 (AFB1) is one of the most important mycotoxins that contaminate food worldwide. Long-term consumption of foods contaminated with AFB1 endangers human health. Detoxification of AFB1 from food improves community health. A Specific approach to aflatoxin reduction is the use of probiotics. Kefir drink is a strong probiotic. The purpose of this study was to investigate the protective effect of kefir drink on AFB1-induced hepatic injury in adult male rats
Methods: In this experimental study, 24 adult rats weighing between 150 and 200 g were used. The rats were randomly divided into 4 groups: 1) control, 2) AFB1 (50 μg/kg body weight), 3) kefir drink (10 mL/kg body weight), and 4) AFB1 + kefir drink. Aflatoxin and kefir drink received through oral gavage. At the end of the experiment (8 weeks), blood and liver samples were collected for different assays. Liver function tests and histopathological examinations were performed. Data were analyzed using 1-way analysis of variance (ANOVA) and at a significance level of <0.05.
Results: Aflatoxin B1 significantly increased serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total bilirubin (T.Bili), as well as decreased total protein (T.P) content, compared to the control group (P < 0.05). Aflatoxin B1 induced histological changes in the liver. The results obtained from the groups treated with kefir drink with and without AFB1 were not significantly different from the control group. Histopathological changes were not found in groups treated with kefir drink with and without AFB1.
Conclusion: The consumption of kefir drink reduced AFB1-induced disruptions in rats’ livers.

Background: Kawasaki disease (KD) is a febrile systemic vasculitis that affects children. Further research is required due to the disease's significance, consequences, and increasing prevalence. This study aimed to determine the frequency of coronary artery complications in patients with KD referred to Taleghani Hospital (Gorgan, Iran) from 2007 to 2017.
Methods: Between 2007 and 2017, 108 cases with a definitive diagnosis of KD were studied retrospectively. Data were obtained from medical records and the patients' biographical, clinical, laboratory, radiographic, and echocardiographic data.
Results: A total of 108 patients diagnosed with KD were involved in the study, 21 (19.44%) of whom showed coronary artery-associated complications. There was no significant difference in clinical and laboratory findings and coronary artery involvement between male and female groups (P-value < 0.05). Left coronary artery (LCA) involvement and the pattern of vascular involvement as ectasia and aneurysm were significantly higher in the echocardiography of the studied patients (P-value = 0.0001).
Conclusion: Kawasaki disease-related coronary artery complication is more common in children under the age of 3, particularly males, in Gorgan. The LCA is the most common site of coronary artery complications in KD children. The findings can improve the prognosis of KD patients and their related heart diseases.

Background: Thyroid disorders are the most common cause of endocrine dysfunction among women of childbearing age. It is well-established that hypothyroid dysfunction can have significant adverse effects on pregnancy and fetal development. This study aimed to determine the prevalence of thyroid disorders among antenatal women and assess the maternal and fetal outcomes in pregnant women with hypothyroid disorders.
Methods: This prospective study was conducted in the antenatal clinic of the Department of Obstetrics and Gynaecology in association with the Biochemistry Department. After obtaining written informed consent, antenatal women aged 18-40 years were included in this study, regardless of their gestational period. Venous blood samples were collected from the antecubital vein, and thyrotropin, free triiodothyronine (free T3), and free thyroxine (free T4) levels were measured. Hypothyroid antenatal women were monitored throughout their pregnancies to evaluate maternal and fetal outcomes.
Results: Among the participants in this study, 149 antenatal women had thyroid disorders, with a prevalence rate of 12.6%. Subclinical hypothyroidism, overt hypothyroidism, subclinical hyperthyroidism, and overt hyperthyroidism were observed in 6.9%, 3.2%, 1.8%, and 0.7% of cases, respectively. Maternal complications included oligohydramnios (5.8%), preeclampsia (13.3%), and preterm delivery (5%), while fetal complications included low birth weight (20.8%), hyperbilirubinemia (9.1%), and neonatal intensive care unit (NICU) admissions (13.3%).
Conclusion: A high prevalence (12.6%) of thyroid disorders, particularly hypothyroidism (10.1%), among pregnant women, emphasizing the importance of routine thyroid testing for all antenatal individuals.

Background: The complete blood count (CBC) profile has been found extremely useful in monitoring the growth of SARS-CoV-2 infection; however, predictive CBC parameters that could be used in the management of the disease may vary in different populations.
Methods: This study comparatively analyzed the CBC profile of SARS-CoV-2 patients (N = 75; confirmed positive by real-time polymerase chain reaction [PCR]) and healthy individuals (confirmed negative by real-time PCR) from Kashmir (north India).
Results: Compared with healthy individuals, most of the CBC parameters (hemoglobin levels [13.43 vs 10.9 g/dL; P = 0.0001], lymphocytes [16.04% vs 30.8%; P = 0.00001], monocytes [5.53% vs 7.53%; P = 0.009], and platelet count [150 vs 186 ×103 µL; P = 0.037]) were significantly low in SARS-CoV-2 infected patients, while neutrophilia was more common in infected patients (76.77% vs 59.26%). Among derived parameters, the neutrophil-to-lymphocyte ratio (NLR; 7.31 vs 2.04; P = 0.001) and derived NLR (d-NLR; 4.43 vs 1.5; P = 0.0002) were significantly high in SARS-CoV-2 patients. Further correlation analysis revealed a significant association of neutrophilia with the severity of the disease in SARS-CoV-2 infected patients. Moreover, receiver operating characteristic (ROC) analysis of derived CBC parameters (NLR, d-NLR, and platelet‐to-lymphocyte ratio [PLR] with disease severity and disease outcome) revealed d-NLR as better predictive marker of disease severity (area under the curve [AUC] = 0.658) and disease outcome (AUC = 0.766) compared to PLR with disease severity (AUC = 0.645) and disease outcome (AUC = 0.693).
Conclusion: We therefore conclude, of the CBC parameters neutrophilia as the marker of disease severity and among derived parameters, d-NLR as an early predictive biomarker of both disease severity and poor disease outcome in SARS-CoV-2 patients.

Background: Certain trace elements, like cerium, have the potential to disrupt iron metabolism. This study explored the impact of cerium on intestinal iron absorption, focusing on the initial stage of iron metabolism. We employed the rat everted gut sac (EGS) segments to assess the interference caused by cerium. The primary objectives of this study were to examine the absorption of cerium in the intestines and to compare iron absorption in the presence and absence of cerium.
Methods: For the EGS experiment, segments of the rat's duodenum, ileum, or jejunum were promptly excised, cut into 5-6 cm segments, and rinsed with a physiological solution. These freshly prepared rat EGS segments were then incubated in Earle's medium containing iron (III) and/or cerium (III). We examined the impact of ascorbic acid, glucose, and different time intervals on the intestinal absorption of cerium and iron. Specifically, we investigated how glucose (5 mM) and ascorbic acid (2.8 mM) affected the absorption of cerium and iron at various concentrations (ranging from 0 to 200 mg/L). Additionally, we assessed the interfering effect of cerium on iron absorption.
Results: The results indicated that the maximum intestinal absorption of Fe (III) and Ce (III) occurred at a concentration of 200 mg/L. Furthermore, it was observed that their uptake increased following the reduction by ascorbic acid. The absorption of these elements also rose in the presence of glucose, suggesting energy-dependent transport. Additionally, a consistent cerium concentration was found to decrease iron absorption by 24.3% (P ≤ 0.05).
Conclusion: Based on the results, cerium likely reduces iron uptake by competing with iron. Cerium can also disrupt iron metabolism and lead to iron-related metabolic disorders. However, further studies at the molecular and intracellular levels are needed to gain a better understanding of this mechanism.

Background: Type 2 DM is a heterogeneous group of disorders characterized by insulin resistance, impaired insulin secretion, increased glucose production, and abnormal fat metabolism. Diabetes mortality primarily results from microvascular complications such as diabetic retinopathy, nephropathy, and neuropathy, as well as macrovascular complications like coronary artery, peripheral vascular, and cerebrovascular diseases. Patients with diabetes usually have changes in adipose tissue metabolism and abnormalities in the secretion of adipokines such as leptin. The present study aims to study the relationship between serum leptin levels and lipid profile parameters among non-obese type 2 diabetes mellitus patients and non-diabetic individuals.
Methods: This hospital-based cross-sectional study was conducted among 41 type 2 diabetic patients and 41 non-diabetic individuals of both sexes between the ages of 40 and 70. Fasting blood glucose (FBS), serum leptin, total cholesterol (TC), triglyceride (TG), and high-density lipoprotein (HDL) levels were assayed.
Results: The mean serum leptin levels among diabetic patients were lower than those of non-diabetic individuals, and this difference in mean was statistically significant. The study showed a significant negative correlation between serum leptin, TC, TG, and low-density lipoprotein (LDL), and a positive correlation with HDL. In the final regression model, serum leptin showed a statistically significant association with FBS and HDL.
Conclusion: This study demonstrated that serum leptin levels can be a strong predictor of low HDL levels in diabetic patients. It can also contribute to raised levels of total cholesterol, triglyceride, and LDL, which are responsible for macrovascular complications in diabetics.

Background: Musculoskeletal disorders are common in patients with hypothyroidism, and are also observed in thyrotoxicosis. Creatine kinase (CK) is present in the muscles and is involved in energy metabolism. This study aimed to estimate the serum CK levels in patients with hypothyroidism, hyperthyroidism, and healthy individuals. Moreover, the correlation of CK levels with markers of thyroid function is assessed.
Methods: A total of 120 patients with hypothyroid and 120 with hyperthyroid were compared with 120 healthy individuals aged 20-60 years. The thyroid status was assessed by determining the serum thyroid-stimulating hormone (TSH) and free thyroxine (fT4) using chemiluminescent immunoassay. Serum CK was measured the by kinetic method. Statistical analysis was performed by analysis of variance and Pearson’s correlation to investigate the correlations between CK and thyroid hormones.
Results: A significant increase (P<0.0001) and a significant decrease (P<0.0001) in serum CK were observed in hypothyroid patients (253.98±129.04 IU/L) and in hyperthyroid patients (34.68±13.15 IU/L), respectively, compared to the control group (72.9±29.01 IU/L). A negative correlation was found between fT4 and CK (r: -0.4253, P<0.0005).
Conclusion: It could be concluded that CK activity in serum may be a useful additional test in thyroid disorders.

Background: Anti-diabetic properties of several Ficus species have been explored in animal studies; nevertheless, there is a dearth of research on the hypoglycemic effects of the bark of Ficus Lacor Buch.-Ham. To address this knowledge gap, this study was conducted to assess the hypoglycemic activity of an aqueous extract derived from the bark of Ficus Lacor Buch.-Ham in diabetic rabbits.
Methods: Diabetes was induced in rabbits using alloxan monohydrate (120 mg/kg intravenously). A total of thirty-six rabbits were divided into six groups, each consisting of six animals. The control groups comprised a non-diabetic control group and a diabetic control group. Two test groups, designated as the low-dose and high-dose extract group, received Ficus Lacor extract orally at doses of 100 and 200 mg/kg, respectively, for 6 weeks. Metformin was utilized as an active control group. To evaluate the hypoglycemic effects in normal rabbits, a group of non-diabetic rabbits received Ficus Lacor extract at a dose of 200 mg/kg. Fasting and post-prandial blood sugar levels were monitored on a weekly basis for 6 weeks and subsequently compared. The percentage reduction in blood sugar levels was calculated for each group and compared among the study groups.
Results: At the end of the 6-week, the low-dose Ficus Lacor extract led to an average reduction of 38.3% in FBS and 40.5% in PP2BS, while the high-dose Ficus Lacor extract resulted in an average reduction of 35.3% in FBS and 36.3% in PP2BS.
Conclusion: Aqueous extract of bark of Ficus Lacor demonstrates significant hypoglycemic activity.
