The aim of the present study was to assess the ototoxicity of kanamycin sulfate (KM) in adult rats and its underlying mechanism. Forty male Sprague-Dawley rats (6-7 weeks old) were randomly divided into the experimental group and the control group. The animals in the experimental group were injected subcutaneously with KM (500 mg/kg per day) for two weeks, and the control group received equal v...

This experiment was conducted, to study the effect of planting time and planting density on savory (Satureja sahendica Bornm.) in 2012 in Alborz Research Station, Research Institute of Forests and Rangelands, Karaj, Iran. The experiment was carried out in split plot in time in the form of a randomized complete block design with three replicates. The main plots were planting times in two levels ...

INTRODUCTION Treatment of the severe forms of acne vulgaris remains a challenge. Isotretinoin is a drug often used in these cases. Retinoids affect the mechanisms that play a role in the pathogenesis of acne, reduce the production of sebum and sizes of the sebaceous glands. However, isotretinoin appears to have undesirable side effects in the skin, mucous membranes and hair. AIM THE AIM OF TH...

The objective of this study was to determine the effect of platelet-rich fibrin matrix (PRFM) treatment on androgenetic alopecia. Prospective cohort study of 15 (9 male and 6 female) subjects with androgenetic alopecia for at least 1 year who were treated with intradermal injections of autologous PRFM three times on a monthly basis. Hair density indices were measured in triplicate in the same a...

Structural and functional studies of the gene coding for the low density lipoprotein receptor in patients with familial hypercholesterolemia have uncovered over 180 mutant alleles of the gene. Although the classical familial hypercholesterolemia phenotype is well known, the range of phenotypic variability in lipid traits associated with particular mutations in familial hypercholesterolemia has ...

Chemotherapy-induced alopecia is a major problem in clinical oncology. Doxorubicin, a widely used cancer chemotherapy drug, induces disruption of the hair cycle and subsequent alopecia. We show in this report that doxorubicin causes disruption of the hair-follicle-associated blood vessel network resulting in a greatly reduced density of these blood vessels. Dystrophic hair follicles were also o...
