Abstract

Background and Objective: Attention deficit hyperactivity disorder (ADHD) is the most common in psychology and Methylphenidate hydrochloride (MPH) is one of the most frequently prescribed pediatric medicine. This study was done to determine the effect of Methylphenidate hydrochloride on ovarian and pituitary gonadotropin hormone in peripubertal mice Materials and Methods: This experimental study was done on 40 preipubertal female mice (BALB/c) with three weeks age and approximate 12-15 gram. The mice were allocated randomly in one control and three experimental groups, designated as I, II and III. Animals in group I, II and III were received by gavage Methylphenidate hydrochloride with 2, 5 and 10 mg/kg body weight for six days, respectively. At the end of experiment body weight, serum estrogen, progesterone and pituitary gonadotropins were measured. Morphometric and histopathological evaluation of ovary were examined. Data were analyzed using SPSS-17, ANOVA and Tukey tests. Results: The body weight and ovary dimensions of animals in experimental groups were reduced significantly in comparison with control (P<0.05). Abnormal cells, structural alternations of granules cells and follicular growth abnormality were observed in experimental groups I and III in compare to control group. A significant reduction of estrogen, in group I, progesterone levels in group I and III were observed in comparison with the controls (P<0.05). Conclusion: This study showed that the Methylphenidate hydrochloride administration induces the reduction of body weight, ovary dimensions and hormones.

Abstract

Background and Objective: Nicotine is an addictive substance and Ritalin is a medicine which has been prescribed for treatment of hyperactivity / attention deficit disorder (ADHD). This study was done to evaluate the effect of Ritalin and nicotine and combination of Ritalin and nicotine on daily sperm production and epididymal sperm reserve in mice. Methods: In this experimental study, 120 adult male BALB/c mice were randomly allocated into one control group and 11 experimental (treatment) groups. Animals, in the first, second and third treated groups were received nicotine at the doses of 100, 200 and 400 microgr/kg/bw, respectively. Mice in fourth and fifth treated groups were received Ritalin at doses of 2 and 10 mg/kg/bw, respectively. Animals in sixth and seventh treatment groups were received nicotine in 400 microgr/kg/bw and Ritalin in 2 and 10 mg/kg/bw and in eighth and ninth groups, nicotine at dose of 200 microgr/kg/bw and Ritalin at doses of 2 and 10 mg/kg/bw, respectively. Animals in tenth and eleventh treated groups were received nicotine as dose of 100 microgr/kg/bw and Ritalin at doses of 2 and 10 mg/kg/bw, respectively. Ritalin and nicotine were administrated orally for 40 days. At the end of study, daily sperm production and epididymal sperm reserve were measeared. Results: The daily sperm production was significantly reduced in the groups with high consumption doses of nicotine and different doses of Ritalin and the majority of groups which used the combination of Ritalin and nicotine (P<0.05). The epididiymal sperm reserve was significantly increased in experimental groups of 8, 9, 10 and 11 which were received the combination of Ritalin and nicotine in different doses (P<0.05). Conclusion: The combination of Ritalin and nicotine reduces daily sperm production and it incereases epididiymal sperm reserve in adult BALB/c mice.

Abstract

Background and Objective: Soybean as a cheap protein and without side effects has been introduced to food industry. This study carried out to determine the effect of diet containing soybean on histology and histomorphometry of duodenal villi and serum levels of Calcium, Phosphorus and Glucose in mice.

Methods: In this experimental study, 30 female immature BALB/c mice with 3 weeks of age were randomly allocated into control, and experimental 1 and 2. The control group was fed a diet with complete protein. Animals in the experimental 1 and 2 were received a diet of complete protein with 40% soybean and 20% soybean, respectively. After 3 months the mice were anesthetized and blood samples were taken from the heart for determining serum level of Calcium, Phosphorus and glucose. Duodenum specimens from were prepared and stained with hematoxylin and eosin.

Results: Tissue structure of duodenum in experimental groups in compare to control group was not significantly changed, except for some scant specimens who showed some degrees of destruction in villi apicese. In histomorphometrical evaluation, the thickness of sub - mucosa and musculature were significantly increased in experimental groups compared to the controls group (P<0.05). The height of villi, depth of crypts and serum Glucose level were significantly reduced in experimental groups compared to the controls group (P<0.05), whereas the level of Calcium was significantly increased in experimental with the control group (P<0.05), but the level of Phosphorus did not show any significant changes in experimental groups compared to the controls.

Conclusion: Long term consumption of soybean can induce significant alteration in serum Calcium and glucose level, thickness of sub mucosa and musculature, the height of villi and depth of crypt in duodenum.

Abstract

Background and Objective: Sodium levothyroxine is one of the common medicines used for treatment of hypothyroidism and thyroid cancer. The study was done to determine the effect of sodium levothyroxine on knee articular cartilage tidemark integrity, plateau tibia cartilage thickness (calcified and non-calcified) and liver enzymes in induced hypothyroidism rats.
Methods: In this experimental study, 50 adult female BALB/c mice, weighting 25-30 grams were randomly allocated into one control and four experimental groups. Animals in control did not receive any medicine. Animals in the second group were received different increasing doses of sodium levothyroxine daily for 8 weeks. Animals in the third group were received constantly high dose of levothyroxine daily for 8 weeks. In the fourth group, the animals became hypothyroid with propylthiouracil (PTU). In the fifth group, animals with hypothyroidism were received sodium levothyroxine by gavage same as group 2. After 8 weeks serum samples were taken to determine ALT, AST and ALP. The plateau tibia cartilage stained with hematoxylin-eosin. Histologic changes evaluated by light microscopy. Using a light microscope equipped with camera, the samples were photographed and using a computer equipped with axiovision software. Cartilage (calcified and non-calcified) thickness measured in micrometer. The integrity of tidemark line on hematoxylin-eosin staining also evaluated.
Results: The results of the present study showed separation, disruption and destruction in tidemark line in group 3 (the group with high dosage of sodium levothyroxine from the beginning of the treatment). The total cartilage and non-calcified part thickness in groups 3, 4, 5 were reduced and in group 3 showed significant reduction (P<0.05). Calcified cartilage thickness in all groups were reduced and in group 3 showed significant reduction (P<0.05). ALT level decreased in all groups compared to control group but only in the second and third groups, the decrease of ALT was significant (P<0.05). AST serum level in all groups significantly increased in compared to control group (P<0.05). ALP serum level in all groups increased compared to the control group, but this increase was significant only in the groups 4, 5.
Conclusion: Consumption of sodium levothyroxine with constantly high dose can cause severe alteration in knee joint cartilage in hypothyroidism rats.

Abstract

Background and Objective: Molybdenum trioxide (MoO3) is a type of nanoparticle used in the industry as an antibacterial agent. The kidney is one of the most important organs in the body, responsible for filtering waste products and regulating blood factors that are affected by various agents. Due to the widespread use of MoO3 in disinfecting operating room equipment and the importance of renal glomeruli in blood plasma purification, this study aimed to determine the effect of molybdenum trioxide nanoparticles on rat kidneys.
Methods: In this experimental study, thirty Wistar rats weighing 250-300 g were randomly divided into five groups (n=6), including a control group, a sham group (receiving normal saline), and three experimental groups (receiving MoO3 at doses of 50, 100, and 200 mg/kg/bw IP). Intraperitoneal injections were given for 35 days. After the treatment period, the animals were anesthetized, and blood samples were collected from the heart. The right kidney was then removed, and after tissue preparation, the samples were examined by stereology to determine changes in the volume of cortex, medulla, urinary space, renal body, and glomeruli.
Results: Significant increases in urinary space volume were observed in the groups receiving MoO3, and a decrease in medulla volume was observed in the group receiving a dose of 200 mg/kg/bw compared to the control and sham groups (P<0.05). A significant increase in cortex volume was observed in the group receiving nanoparticles at a dose of 50 mg/kg/bw compared to the control and sham groups. MoO3 caused weight reduction in animals, as well as an increase in urea and a decrease in renal volume (P<0.05).
Conclusion: Molybdenum trioxide nanoparticles can cause changes in the morphology of rats' kidneys.
