Calcium plays an important role in the pathophysiology of essential hypertension. Serum calcium levels were measured in 117 subjects with essential hypertension and 77 first-degree relatives. The results showed that serum calcium levels were significantly (p<0.01) decreased in both males and females with essential hypertension and their first-degree relatives when compared with the normotensive controls. This is the first study in Indian population.

An 11 year old male non-descript dog was presented with the history of frequent vomition and progressive weight loss for the past one month. The dog was dull, dehydrated, anaemic and emasciated. Positive contrast survey radiographs, revealed delayed gastrointestinal transit time and absence of foreign body. Exploratory laparatomy was done which revealed thickening of entire layer of the gastric wall with pylorus and the histopathology revealed gastric adenocarcinoma. Since the tumor was spread to the full thickness of the stomach wall including pylorus, the prognosis was informed to the owner and euthanasia was advised.
