Aim and Objective: The study was conducted to see the effects of dexamethasone (synthetic corticosteroid) on involution ofhyperplastic thyroid gland in albino rats, and to evaluate its uses in thyroid diseases. Study Design: Comparative histological study done inPostgraduate Medical Institute Lahore in 1998. Materials and methods: 54 adult male rats were taken and divided at random into control grouphaving 27 rats and experimental groups containing 27 rats. Control group was given normal diet along with 2 microgram of Potassium iodidefor 21 days while experimental groups further subdivided into group A having 3 rats and group B and C containing 12 rats each. All theexperimental groups were treated with Thiourea. Group A was sacrificed on day 22 after withdrawal of thiourea. Group B was given Potassiumiodide after stoppage of thiourea on day 21 and were sacrificed on days 22, 26, 30 and 50 in 4 sub groups (B1- B4). Group C was injectedDexamethasone daily from day 22 to day 50 and sacrificed on same days in 4 subgroups (C1-C2) to study involution process. Results:Histologically experimental group A exhibited significant increase in width and length of follicular cells lining the small sized follicles havingscanty colloid. The results of experimental subgroups B revealed early and complete involution whereas subgroups C showed significantlypersistent hyperplastic changes in the form of tall follicular cells lining small empty follicles. Conclusion: Thus it was concluded thatdexamehasone did retain hyperplastic changes during involution process, so steroid should consciously be used in thyroid diseases.

Introduction: Cyclophosphamide is one of the alkylating chemotherapeutic drug used in cancer patients that has antifertility effects on female gonads. Ocimum basilicum is a natural herb rich in polyphenols and is known to improve fertility. Aims & Objectives: The study was designed to evaluate the role of natural herb, Ocimum basilicum extract, as a preventive agent against ovarian follicular toxicity induced by cyclophosphamide. Place and duration of study: This experimental study was performed in the Department of Anatomy, Shaikh Zayed Postgraduate Medical Institute, Lahore. The duration of study was 8 months. Material & Methods: 45 female albino rats were divided equally in control group A, experimental group B and group C each contained 15 rats. Group A rats received single dose of 150 mg/kg normal saline intraperitoneally on 8th day of experiment, while group B was given single intraperitoneal dose of 150 mg/kg cyclophosphamide at day 8 of experiment. Group C rats were pretreated with methanolic basil (Ocimum basilicum) seeds extract for 7 days followed by single intraperitoneal dose of 150 mg/kg cyclophosphamide at day 8 of experiment. All the rats were dissected 48 hours after the last dose. Results: Graafian follicles were atrophied showing atretic granulosa cells in group B when compared with control group A with p value <0.001. However, significant improvement in status of Graafian follicles was observed in group C, when compared with group B with p value <0.025. Conclusion: This study depicts that basil seeds extract can prevent the cellular toxicity in Graafian follicles caused by cyclophosphamide treatment. So the use of basil seeds during chemotherapy can significantly limit its toxic effects on Graafian follicles.

Aim: This study was aimed to evaluate the effect of methanol extract of Napoleonae imperialis leaves against methotrexate renal damage in albino rats. Methodology: Thirty (30) male albino rats of mean weight 130 g were used for this study. The animals for the study were grouped into five (5) of six (6) rats each. Group A (normal control) received feed and water only and Group B (positive control) was induced with methotrexate without treatment. Test groups (C and D) were orally given 250 mg and 500 mg/kg b.wt of leaves extract, and group E was orally given the extract only (500 mg/kg b.wt) respectively for 14 days. All the rats used in this study were initially subjected to renal damage using 0.5 ml/kg of methotrexate except the normal control group. The rats were sacrificed after 14 days and the blood samples were collected for biochemical analysis, Results: From the result obtained, there was a significant (p< 0.05) decrease in the groups that received 250 mg/kg and 500 mg/kg b.wt of the plant extract in (Urea, Creatinine and Na+), and a significant increase (p< 0.05) in K+ and Cl-. Also there was a significant (p< 0.05) decrease in (Urea, Creatinine, and Na+) in comparison with the control groups and the group that received the extract only (500 mg/kg b.wt), and a significant increase (p< 0.05) in (K+ and Na+). Conclusion: The study indicates that the methanol extract of Napoleonae imperialis leaves may have exerted renal functioning effects in albino rats, and may also be used pharmacologically in the management of organ toxicity.

The present study was designed to evaluate the antiurolithiatic activity of Prosopis farcta (P. farcta) ethanol fruit extract in ethylene glycol (EG) induced urolithiasis in male albino rats. Lithiasis was induced by oral administration of EG 1% in male albino rats for 28 days. Seventy eight male albino rats weighing 250-300g were used and divided into six experimental groups. Group A is a control group received standard rat chow and tap water ad libitum, while, rest of groups namely group B, C, D, E, F animals received 1% EG in water for 28 days, then from day 15 to day 28 in addition to EG administration, group C received cystone, group D, E and F received 100, 200 and 300 mg/kg body weight (B.W.) of ethanol fruit extract of P. farcta respectively. On day 28, blood was collected for serum biochemical (serum uric acid, creatinine, urea, electrolytes measurements, malondialdehyde (MDA) and superoxide dismutase (SOD)) determinations. While urine was collected to microscopic analysis of formed crystals besides the kidney weight/ B.W. ratio and B.W. gain/ loss values were determined. Intermediate dose (200mg/kg B.W.) of P. farcta extract significantly decreased serum creatinine, urea, MDA and non-significantly recovered SOD toward control value in group E as compared to group B, also significant elevation in kidney weight/ B.W. ratio and reduction in B.W. gains in group B occurred as compared with group A. In conclusion: P. farcta fruit extract has potentially therapeutic effects on EG induced kidney stone which can be used as effective antiurolithiatic agent rather than cystone.

Background: Thyroxine has shown beneficial effects on intelligence, learning, and memory process in patients of congenital hypothyroidism. Minocycline has been used in clinical practice for various indications and reported to have anti-thyroid effects. This study was specifically designed to observe the role of thyroxine on minocycline induced damage to thyroid gland. Methods: This experimental study was undertaken at Anatomy department of BMSI, JPMC, Karachi, for eight weeks, from October to November 2019. Thirty adult (10-12 months) male guinea pigs, weighing from 450-650 gm were obtained and divided into 3 groups. Group A served as control, group B was given Minocycline 0.02mg/gram/day once daily and group C was administered Minocycline in similar amount as group B along with thyroxine 0.5µg/gram/day for the same duration. Dosing was continued for 8 weeks, at the completion of which all the animals were sacrificed. Thyroid gland was processed and tissue sections were stained with Haematoxylin and Eosin for morphology. Results: The absolute weight of thyroid gland was significantly increased (p<0.001) in minocycline treated group B animals compared to the control animals, whereas substantial decrease (p<0.01) in absolute weight of thyroid gland was witnessed in group C in comparison to group B animals. The follicular cells showed hypertrophy and shrinkage of colloid in the thyroid follicles. These changes were prevented when animals were co-administered with thyroxine and minocycline in Group C. Conclusion: Concomitant administration of thyroxine with the antimicrobial drug minocycline showed protective effects of thyroxine on Minocycline induced damage to thyroid gland of animals.

Background: The position and size of isthmus of thyroid gland varies considerably in human with age, sex, physiologic state, race and geographical location and sometimes the isthmus may be absent. So this study was designed to find out the macroscopic differences in isthmus of thyroid gland of different age and sex groups in Bangladeshi people.Objective: To record the macroscopic characteristics of isthmus of thyroid gland with advancing age in both sexes with a view to help establishing normal standard of Bangladeshi people.Materials and Methods: This descriptive cross-sectional study was carried out on 54 autopsied human thyroid glands aged 5 to 65 years. Thyroid glands were collected from unclaimed dead bodies autopsied in the morgue of Sylhet M. A. G. Osmani Medical College, Sylhet. The collected specimens were divided into groups –– A (20 years and below), B (21 to 50 years) and C (50 years and above). All specimens were examined morphologically by careful gross dissection method.Results: The isthmus was absent in 5.56% cases. In most of the cases (35.29%) it was against the 1st–4th tracheal rings. There was significant difference in length between Group A and Group C (p<0.05) and in breadth between Group A and Group C and between Group B and Group C (p<0.05). No significant difference was found in length, breadth and thickness of isthmus of the thyroid gland between males and females.Conclusion: The presence or absence, positional change and variation in gross dimension of isthmus of thyroid gland were evident in human. The macroscopic difference was found with increasing age but not with sex.J Enam Med Col 2017; 7(1): 15-19
