RESUMEN
Hypercholesterolemia and atherosclerosis are the most common causes of mortality and disability, especially in developed countries. The aim of this research was to evaluate the effect of Biebersteina multifida DC. root extract on HDL and LDL blood level. In this experimental study, 35 male Balb/c mice were randomly divided in five groups such control, sham, and experimental groups which received Biebersteina multifida DC. root extract with the doses of 4, 5 and 10 mg/kg; three last groups were daily fed orally, for thirty days. HDL and LDL blood serum levels were measured, in the last day and compared with control and sham groups. The results after 30 days gavage of 4, 5 and 10 mg/kg of Biebersteinia Multifida DC. root extract showed that the root extract decrease of LDL level significantly. The doses of 4, 5 mg/kg of the root extract were the effective dose in decreasing the serum HDL level. However, 10 mg/kg dose of root extract has no significant effect on HDL level in comparison with control and sham groups. 10 mg/kg of root extract had the maximum effect on reducing LDL level. According to this study, it is suggested that the root extract of Biebersteinia multifida DC. can be efficient to reduce the level of HDL and LDL in blood serum
RESUMEN
Hair transplantation is the main therapeutic method for androgenic alopecia. Improvement of the hair transplant techniques with more acceptable appearance of the transplanted hair has made this method more popular. Nowadays, for more acceptable appearance of transplanted hair, every follicle is transplanted separately or in small groups which is a time consuming procedure and exposes the follicles to environmental stressors. The new device that we introduce here can be time saving and decreases the exposure time to stressors. This device was named Micro-implant and we used it for hair transplantation in a 45 years old man with androgenic alopecia. After informed consent and adequate explanations, necessary laboratory tests were performed which their results were normal. Three 10×2 cm grafts were resected from occipital area. The grafts were placed into sterile physiologic buffer rapidly and then divided by a scalpel into small pieces, each containing 1-4 follicles. These graft units were transplanted into the frontal bald area by means of the Micro-implant. Use of this device will reduce transplantation time notably and maintain the viability of the transplanted follicles which ensure success of transplantation
