Effect of ninhydrin on the biochemical and histopathological changes induced by ethanol in gastric mucosa of rats.

Studies on the effect of ninhydrin in the normal gastric mucosa and against the ethanol induced gastric injury were undertaken in rats in view of the presence of a carbonyl function as well as hydroxyl groups in its chemical structure. In spite of its potentials to generate hydroxyl radicals, it is deemed to possess antioxidant property by virtue of its electrophilic nature. Recent studies have shown gastro-protection to mediate through a reaction between the electrophilic compounds and sulfhydryl groups of the mucosa.

Effect of camel urine on the cytological and biochemical changes induced by cyclophosphamide in mice.

Camel urine treatment was found to cause a significant cytotoxic effect in the bone marrow cells of mice. This cytotoxicity at higher doses was comparable with that of standard drug cyclophosphamide (CP). However, unlike CP, the camel urine treatment failed to induce any clastogenicity.

Splenic preservation after traumatic rupture. A remote hospital experience.

Objective: The aim of this study is to describe the outcome of treatment modalities, the length of hospital stay and blood transfusion requirements of patients with traumatic splenic rupture. It also discusses the pros and cons of each treatment given, to determine its feasibility and pre-requisites in a set-up similar to this one. SET-UP: The Royal Commission Medical Centre is a 340-bed secondary care facility located in Yanbu Industrial City, in the western part of Saudi Arabia.

Effect of desferrioxamine on cisplatin-induced nephrotoxicity in normal rats.

Biochemical and histological evaluations of the effects of the iron chelator desferrioxamine on the nephrotoxicity induced by cisplatin in normal rats were carried out. A single dose of cisplatin (7.5 mg/kg, intravenously) caused nephrotoxicity that manifested biochemically as an elevation of blood urea nitrogen, serum creatinine and an increase in the kidney weight as a percent of body weight.

Diltiazem potentiation of doxorubicin cytotoxicity and cellular uptake in Ehrlich ascites carcinoma cells.

The calcium channel blocker diltiazem, which possesses coronary vasodilator activity, greatly enhanced the cytotoxicity of doxorubicin in Ehrlich ascites carcinoma cells. 20% of the doxorubicin-treated tumor-bearing animals (2 mg/kg, every other day, three doses) survived, with a mean survival time of 35 days. However, pretreatment with diltiazem increased survival to 70% with a mean survival time of 43 days.
