Primary papillary serous cystadenocarcinoma of broad ligament

A rare case of an advanced primary broad ligament carcinoma is discussed, with a review of the literature regarding its incidence, presentation and management. This patient showed a complete response to adjuvant cisplatin-based chemotherapy following panhysterectomy and is presently without any evidence of disease, 15 months after completion of her treatment.     

Zinc feeding and fertility of male rats

Supplementation of the diet of adult male rats with 4,000 ppm zinc as ZnSO4 for 30 to 32 days increased the zinc content in the testis and sperm by 25 and 18 per cent respectively, but did not change the same in accessory reproductive tissues, e.g. epididymis, seminal vesicle and prostate. The incidence of conception from mating between normal females and zinc fed males was lower as compared to mating between normal females and control males. This observation indicated reduced fertility of the males resulting from additional zinc ingestion. Motility of the sperm collected from the epididymis (tail) of the zinc treated rats was found to be inhibited. It has been suggested that excess zinc in the sperm was responsible for their poor motility and hence a reduced fertilising capacity.     

Gun shot wound neck

All penetrating neck wounds are potentially very dangerous and require emergency treatment. The choice of treatment for the stable patient remains controversial, a number of studies encouraging mandatory surgical exploration and a similar number encourage selective surgical exploration. Knowledge of the physical properties of the penetrating object or weapon can help to determine a treatment plan and predict the risk of injury- All tracheal and esophageal injuries with structural damage should be repaired primarily. A case of Gun Shot Wound Neck was air evacuated to Army Hospital R & R Delhi Cantt in a tracheostomised state. Patient was evaluated in detail, he had trachea esophageal fistula. The management of this case is discussed along with principles of management of war injuries.     

Studies on the effects of Pluchea indica less root extract on gastroduodenal ulcer models in rats and guineapigs

The methanolic fraction of P. indica root extract was found to possess significant antiulcer activity in different experimental animal models. In preventive antiulcer tests, significant protective actions in acetylsalicylic acid, serotonin and indomethacin-induced gastric lesions were observed in experimental rats. The extract also afforded significant protection to chemically-induced duodenal lesion in guineapigs. Significant enhancement of healing process in acetic acid-induced chronic gastric lesions were also observed in the extract-treated animals.     

Intracranial Non-Hodgkin’s MALT lymphoma mimicking a large convexity meningioma

Summary Primary presentation of an intradural Non-Hodgkin’s lymphoma is rare. Recently these B cell lymphomas of mucosa associated lymphoid tissue (MALT) have gained acceptance as an important pathological subtype and are distinguishable from other primary CNS lymphomas that exhibit aggressive behaviour. Over the past decade a number of these lesions have been reported to resemble a meningioma both intra-operatively and radiologically. The authors outline such a case of marginal zone B cell lymphoma that clinically and radiologically resembled a meningioma. This case illustrates the rare occurrence of low grade dural B cell lymphoma and the need to consider this entity in the differential diagnosis of CNS lesions, if appropriate targeted therapy is to be administered.     

METH1在酵母双杂交系统中的表达及对报告基因激活作用的检测

目的通过观察血管生成抑制因子METH1的cDNA片段在酵母双杂交中的表达及检测其对报告基因有无激活作用，为进一步明确METHI抑制增生性瘢痕的分子机制奠定基础。方法采用酵母双杂交Ga14系统3，经PCR扩增子METH1的cDNA片段，分别克隆入pUC19质粒，经测序正确后。再分别亚克隆入酵母双杂交诱饵载体pGBKT7中。将重组质粒导入酵母菌AH109，检测其表达产物在酵母细胞中对报告基因的激活作用。结果成功获得METH1的cDNA片段，该片段所表达的蛋白对酵母菌AH109无毒性，且对报告基因无激活作用。结论血管生成抑制因子METH1蛋白活性区在酵母双杂交系统中的表达产物。可作为诱饵蛋白进行相互作用蛋白的筛选研究。
