The stimulative effect of 17 beta-estradiol on the growth of androgen-dependent Shionogi carcinoma 115 and estrogen receptor in the tumor were studied. The incorporation of 17 beta-[3H]estradiol following a single injection of 17 beta-[3H]estradiol into tumor-bearing animals was 5- to 20-fold higher in the tumor than in the spleen and blood. Scatchard plot analyses showed that the tumor cytosol...

Background: T-2 mycotoxin belongs to the Trichothecene family and has damaging effects on the immune system. Objective: To investigate the toxic effect of T-2 toxin on the percentage of peripheral blood B lymphocytes and the potential protective role of selenium and vitamin E. Method: Frequencies of B lymphocytes (CD19+ ) were analyzed after injection of sublethal doses of T-2 toxin into Balb/c...

OBJECTIVE To evaluate effects of subacromial bursa injection with steroid according to dosage and to investigate whether hyaluronidase can reduce steroid dosage. METHODS Thirty patients with periarticular shoulder disorder were assigned to receive subacromial bursa injection once a week for two consecutive weeks. Ten patients (group A) underwent subacromial bursa injection with triamcinolone ...

In mammals, procedures such as handling, restraint, or exposure to open spaces induces an increase in body temperature (T(b)). The increase in temperature shares some characteristics with pyrogen-induced fever and so is often called "stress fever." Birds also respond to acute handling with a stress fever, which may confound thermoregulatory studies that involve animal restraint. We have measure...

Background and aims: Hepatitis B virus (HBV) is one of the important public health diseases in Iran.Therefore, to control the prevalence of the disease, knowledge is required regarding the risk factor ofHBV. Accordingly, the aim of this study was to determine the risk factors of HB transmission.Methods: A retrospective case-control study was conducted on the possible risk fact...

OBJECTIVES We evaluated cross-linked hyaluronic acid (hylan B gel) as a scaffold for tissue regeneration and mucosal wave restoration in carbon dioxide laser-ablated canine vocal folds. METHODS Five beagles underwent stroboscopy before ablation of the left vocal fold with a carbon dioxide laser. Four weeks later, stroboscopy was repeated before and after submucosal injection of hylan B gel in...

OBJECTIVE To investigate Botulinum toxin type B (BNT-B) injection's effect and duration depending on dose for patients with brain lesion. METHOD Twenty one patients with brain lesion and severe drooling were included and divided into three groups. All patients received conventional dysphagia therapy. Group A patients (n=7) received an injection of 1,500 units and group B patients (n=7) receiv...
