Abstract Introduction: Calabash chalk is a naturally occurring mineral, chiefly composed of fossilized sea shells. It is prepared from clay and mud mixed with other ingredients, including lead, arsenic, sand and wood ash. Clay consumption is correlated with pregnancy, and also to eliminate morning sickness in women. The aim of this study is to evaluate the effects of calabash chalk on the ovarian function in adult female Wistar rats. Methods: Eighteen (18) adult female Wistar rats. Group A served as the control group, group B received 40 mg/kg body weight of Non-salted calabash chalk while group C received 40 mg/kg body weight of Salted calabash chalk for 14 days. On day 15, the animals were sacrificed for histological and biochemical examination. Results: Results showed a significant (P< 0.05) reduction in follicle stimulating hormone (FSH) levels of the treatment groups when compared with the control group and an increase in luteinizing hormone (LH) levels of the treatment groups when compared with the control group. Histological examination of the ovaries showed severe deterioration of the ovarian follicles, necrosis and follicular atresia. Conclusion: Calabash chalk is toxic to ovarian function. These alterations have been shown to be the leading cause ofinfertility in female rats. Hence, proper monitoring, education, and regulation of the product is needed.

Background: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures. Purpose: The study was designed to investigate the effect of Corchorus olitorius extracts on the testis of adult Wistar rats. Method: A total number of thirty two adult Wistar rats weighing between 180 and 200 grammes separated into four groups labeled A,B,C and D respectively were used for the study. Animals in group A which served as the control group were fed with the normal rat chow and water only. The group B rats were administered 100mg/kg body weight of aqueous extract of Corchorus olitorus; while those in group C were administered 500mg/kg body weight of the extract. The group D rats received 1000mg/kg body weight of the extract. For a period of four weeks, the different experimental animal groups received the respective aforementioned treatments once daily, around nine- o’clock in the morning through oral intubation. At the end of the 28 day treatment, the animals were sacrificed and the testes harvested for histological, investigation, and through cardiac puncture, blood samples for some hormonal studies was also collected and investigated using standard laboratory standards. Results: Observations made showed that the extract produced no histological distortions, degenerative or defective effects on the testicular tissues. The testosterone levels of group B, C, and D rats were observed to be significantly higher (P<0.005) than that of the group A (control group).ound: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures.

This study investigated the effect of the crude aqueous extract of Brassica nigra (Black Mustard Seeds) in gestation and on the prefrontal cortex of newborn Wistar rats at different doses following prenatal administration. Eighteen (18) adult female rats weighing an average of 180±10g were used. The female rats were split into 3 groups of six animals; Group A received distilled water throughout gestation, Group B received 200 mg/kg body weight of extract throughout gestation, and Group C received 100 mg/kg body weight of extract throughout gestation). Rat pups from the experimental groups were sacrificed on postnatal days 1, 7, 14, 21, 28, and 35 and subsequently prepared through routine histological and histochemical procedures. Brassica nigra was abortifacient at 200 mg/kg body weight and reduced litter size at 100 mg/kg body weight. No observed physical deformities in pups of treated groups. Comparative prefrontal microarchitecture revealed little to no alteration in the treated group. This study concludes that Brassica nigra (black mustard) is not totally innocuous and as such, should be moderately consumed or totally avoided in pregnancy.Keywords: Brassica nigra; Mustard seeds; Gestation; Neurodevelopment.

This study investigated the effect of hyperthermia on the gonads of the pups of Wistar rats following maternal exposure to brief hyperthermia during pregnancy. Twenty-five pregnant adult female Wistar rats were randomly selected into two groups: Group A (Control) which consisted of 10 female rats and Group B (Experimental) which had 15 female rats. The pregnant dams in the experimental group were exposed to brief hyperthermia for 15 minutes twice daily at 8.00am and 4pm on gestational day (GD) 12-18. The pups produced by the rats were weighed, examined and sacrificed at 35days of post-natal life. Recorded were the microscopic appearances of the gonads while the luminal diameter and thickness of the gonadal vessels were measured and recorded. Data was analysed, mean and standard deviation were generated with student t-test, and p< 0.05 was taken as significant. Maternal exposure to brief hyperthermia during pregnancy significantly reduced the birth weight of the pups in Group B (3.86 ± 0.26g) compared to Group A (4.71 ± 0.18g). The luminal diameters of the testicular and ovarian arteries of the pups in Group B were significantly increased whereas the gonadal vascular arterial wall thicknesses were significantly reduced in comparison with the Group A. Histological examination of the gonads revealed fewer cell population with degeneration and damage to the germinal epithelium of the gonads of the pups in Group B which was more severe in the testes. Maternal exposure to brief hyperthermia during pregnancy has deleterious effects and subsequent destruction of the gonads of pups of Wistar rats and this may interfere with fertility of the pups later. Key Words: brief hyperthermia, gonads, maternal, pregnancy, wistar rats

SUMMARYThe growth and feed intakes of Corriedale wether sheep when grown from 30 to 50 kg body weight by five different growth paths are described.Group A (control) grew continuously (fed ad libitum). After reaching ca; 40 kg body weight, group B and C animals lost 21% of their initial body weight over 9 and 18 weeks and at 122 and 63 g/day, respectively, and began realimentation at 30 kg body weight. Group D and E animals were ca. 50 kg body weight when weight loss was imposed and they lost body weight at similar rates (125 and 157 g/day) respectively. Animals in group D lost 34% of their initial body weight over 18 weeks and began realimentation at 30 kg body weight (the same as groups B and C). Group E animals lost 23% of their initial body weight over 9 weeks to begin realimentation at 35 kg body weight. Except during periods of weight loss, animals were fed ad libitum. Compensatory growth was observed in all groups which had lost weight, with early recovery growth rates 1·6–1·8 times higher than control sheep of the same weight.Rate of body-weight loss did not induce any significant differences in response to realimentation but results (groups B and C) suggest that the more rapid the loss, the more rapid will recovery be during realimentation. When sheep at different body weights lost the same proportion of their initial body weights, the heavier sheep (group E) attained final slaughter weight quicker than the lighter sheep (group B). When the proportion of body weight lost to reach a particular lower body weight was varied (groups B and D), the greater weight loss was associated with higher and more persistent growth rates during realimentation.After weight loss, ad libitum dry-matter intake was significantly lower during the first 10 kg of gain during realimentation in all treatment groups (B, C, D, E) than in control group A. There were no differences between treatment groups in recovery of dry-matter intake.Gross efficiency in all treatment groups was higher than in the control group A during the first 10 kg of recovery of body weight, but it then declined rapidly. This increase in gross efficiency was considered to be due to a combination of increased growth rates, reduced feed intakes and lower maintenance requirements. When the complete growth paths from 30 to 50 kg were considered, there were no significant differences in total feed consumed by the sheep following the five different growth paths.

Introduction: The study aims to evaluate the anti-hyperglycaemic effect of turmeric and the histological changes in the pancreas of adult Wistar rats. Materials and Methods: Forty adult Wistar rats were divided into four groups of [A-D] ten rats per group. Group A was normal control, group B was diabetic control, group C was treated with 300mg/kg weight of extract and group D was 500mg/kg body weight. All animals had access to food and water ad libitum.  Aqueous extract of turmeric was administered orally, once daily for 14 days. The rats were then anaesthetized with dichloromethane before sacrifice and sample collection. Pancreatic tissues were processed, stained using the hematoxylin and eosin (H&E) method. Blood glucose estimation was determined using the glucose oxidase method. Results: The mean body weights of the rats across groups were not statistically significant. Similarly, blood glucose levels across groups revealed a progressive statistically significant increase from group A to D and from day one to day 17. Pairwise comparison of group A with B, C and D showed a statistically significant increase but a comparison of Group B with C and D were not significant. Discussion: There was progressive body weight increase of the rats from day one to the final day across all groups and reduction in the blood glucose levels of the animals treated with 300mg/kg and 500mg/kg body weights, after seven days of treatment, but these, progressively increased with time even with treatment. The overall pancreas features indicate moderate inflammatory changes. Keywords: turmeric, anti- hyperglycemia, alloxan, Wistar rats


OBJECTIVE: To investigate the anti-oxidative and anti-nephrotoxic effects of Resveratrol in cisplatin induced nephrotoxic albino Wistar rats. METHODS: This quasi-experimental study was performed at Isra University, Hyderabad, Pakistan. Thirty male albino Wistar rats were divided into three groups: group-A (control), group-B (cisplatin) and group-C (cisplatin+Resveratrol). Biochemical [serum urea, creatinine and glutathione peroxidase (GPX)] and renal histomorphology was performed in all groups after 21 days of treatment. RESULTS: Difference in mean pre- and post-experimental body weight was observed in all three groups. Mean body weight decreased from 241.7±8.5 gm to 196.50±9.34 gm and from 237±7.4 gm to 207.2±6.56 gm in group-B and group-C respectively. In group-A; mean serum urea was 22.7±2.66 mg/dl, serum creatinine was 0.45±0.05 mg/dl and serum GPX was 1.44±0.13 ηg/ml. In group-B; mean serum urea level was 51±3.65 mg/dl, mean serum creatinine was 0.78±0.05 mg/dl and serum GPX was 0.85±0.11 ηg/ml. In group-C, mean serum urea level was 32.8±1.45 mg/dl, serum creatinine level was 0.41±0.09 mg/dl and serum GPX was 1.53±0.08 ηg/ml. In group-A, renal structure was intact, marked changes were observed in renal histology of group-B while group-C displayed less glomerular damage. The mean distance between visceral and parietal layers of Bowman’s capsule was 69.34±0.87 µm in group-A, 216.5±1.32 µm in group-B while 102.22±1.65 µm in group-C. Areas of peritubular fibrosis and congestion were observed in groups B and C but less prominent in group-C compared with group-B. CONCLUSION: Resveratrol therapy is a potent anti-nephrotoxic regime showing promising results in chemotherapy induced nephrotoxicity and oxidative stress.

The objective of this study was to improve the reproductive efficiency of dairy cows with puerperal metritis (PM) subsequent to retained placenta (RP) using a two-step treatment strategy. A total of 188 postpartum cows, aged from 2 to 8 years, were utilised for 2 experiments. In Experiment 1, cows affected with RP/PM were randomly assigned to two treatment groups. Cows in Group A (n = 17) were treated with 600 mg of ceftiofur intramuscularly for 3 days followed by intrauterine lavage with 0.1% chlorhexidine and infusion with 0.5% povidoneiodine, while cows in Group B (n = 16) received two intrauterine infusions, first with 5 g of oxytetracycline and then with 0.5% povidone-iodine. Cows with normal postpartum findings were regarded as the healthy control group (n = 26). Ultrasonographic examination revealed that the ovarian activities including the appearance of a dominant follicle and days to first ovulation of the cows in Group A during the early postpartum period differed from those of Group B (P < 0.05), which coincided with the results of uterine swabbing for bacteriology. In Experiment 2, cows with normal postpartum findings were allocated to Group D (n = 78), which received an ovulation protocol (GnRH - 7 d PGF2α - 48 h hCG - 24 h AI) on day 50 ± 2 postpartum. Cows affected with PM were randomly divided into two groups, Group E (n = 25) combined the treatments applied in Groups A and D, while Group F (n = 26) repeated the treatment administered in Group E except for uterine lavage. The results indicated that the pregnancy rate within 150 days postpartum and the mean days open in Group E (76.0% and 106.3 ± 4.6 days, respectively) were significantly different from those in Group F (38.5% and 137.9 ± 10.9 days, respectively) (P < 0.05). This study suggests that reproductive efficiency could be improved by using the two-step treatment to regulate uterine involution and an early resumption of ovarian function in cows with RP/PM.

A study to investigate the influence of selenium on final body weight and slaughter traits of Aseel was conducted. Three-weeks-old 120 cockerels from Lakha, Mushki, Peshaweri and Mianwali varieties of Aseel were randomly selected and distributed into four groups, 30 cockerels each, subdivided into 3 treatment groups A, B (experimental groups), and C (control group) with 10 cockerels in each treatment. Birds were assigned three experimental diets. The diet for the birds of group A incorporated 0.3 mg/kg Se-enriched yeast and group B included 0.3 mg/kg sodium selenite, while C was fed the diet without Se (control diet). Final body weight, dressed weight, dressing%, eviscerated weight, eviscerated%; chest, thigh and giblets weight; selenium content in chest and thigh in Se-yeast fed birds were significantly increased than those got sodium selenite or control diet. The study concluded that Se-enriched yeast is more effective in improving body weight and slaughtering characteristics of Aseel.
