[Effectiveness of oxytetracycline and chingamin on cold injury in rats]

The preventive and therapeutical effects of oxytetracycline hydrochloride, 10 mg/kg b.w., and chingamine, 50 mg/kg b.w., were studied in frostbites caused by ethyl chloride. The experiments were conducted on adult albino Wistar rats. The two drugs given orally twice a day for 15 days or more prevented the development of frost bite; clinical, biochemical, and histological parameters becoming normal. Chingamine was found to be more effective, which makes it promising for further experimental and clinical studies.
