The Number of Pherivascular Mastocyt Associate with The Diameter of Blood Vessels in The Mesentary Rats.
Mastocyt dgrenulated can cause vasodilatation of blood vessels, but it is unclear whether there ia a relationship between the number of mastocyt with a diameter of blood vessels. This study aim to determine the relationship between the number of mastocyl pherivascular and diameter of blood vessels. This research is in vivo exploratory research in Wistar rat mesentary which was sensitated with ovalbumin. The diameter of blood vessels at mesentery praparate were measured microcopically using a micrometer scale standards. At large diameter of blood vessels (2.880±0.348) the number of mastocyt was 123±2.3 At medium diameter (0.961±0.043). The number of mastocyt was 3.5±1.3. Calculations area on the microscope visual feld was divided into four areas (counting area), there were zone 1. Zone 2. Zone 3 and zone 3 and 4. Statistical analysis showed that the correlation between the number of mastocyt at zone 1 and the diameter of blood vesseis was 0,904 at 1% significance level. Similar to that at zone 2 (r=0,892), zone 3 and zone 4 (r=0,940). We conclude there was a significant relationship between the number of mastocyt and the diameter of blood vesseis.
