Evaluation of serum lipids and lipoproteins and their correlations together, and with thyroid hormones in gray necked ostrich

To evaluate the concentrations of serum lipids and lipoproteins and their correlations together and with thyroid hormones in gray necked ostrich [Struthio camelus], the serum levels of cholesterol, triglyceride, total lipids, very low density lipoproteins [VLDL-cholesterol], low density lipoproteins [LDL-cholesterol] and high density lipoproteins [HDL-cholesterol] and their correlations with tri-iodothyronine and thyroxine hormones were measured in 50 clinically healthy gray necked ostriches [30 male and 20 female] which were divided into three age groups. The mean serum concentrations +/- SE of cholesterol, triglyceride, total lipids, HDL-cholesterol, LDL-cholesterol and VLDL-cholesterol were 102.62 +/-30.23, 120.22 +/-54.25, 458.96 +/- 106.37, 29.96 +/-6.737, 48.61 +/-23.11 and 24.04 +/- 10.85 mgr/dL, respectively. Also, the mean serum concentrations +/- SE of thyroxin and tri-iodothyronine hormones were 7.89 +/- 1.52 microg/dL and 2.54 +/- 1.31 ngr/mL, respectively

The mean serum concentration of the cholesterol, total lipids and T3 had a negative significant correlation and age [r = -0.340, P=0.016], [r = -0.335, P=0.017], [r = -0.282, P=0.047], and a marginally negative significant correlation was detected between HDL-cholesterol with age [r = -0.271, P=0.056]

Serum thyroxine and tri-iodothyronine had no significant correlation with the lipids and lipoprotein concentrations [r = -0.115, P=0.083], [r = -0.187, P=0.070]?

effect of three-dimensional model on anatomy learning of middle ear

The aim of this study was to study the effect of three-dimensional model in learning the anatomy of middle ear. The study was conducted at Artesh University of Medical Sciences in 3 phases in 2007: 1- preparation of three-dimensional model with reference to the Gray's Anatomy for Students [2005-1[st] edition], 2- dividing medical and nursing students into 4 grouos accidentally, teaching with lecture and powerpoint slides to control groups and additional teaching with three-dimensional model to study groups, 3- taking similar pre-test and post-test exam and statistical analysis. Analysis of pre-test and post-test scores in each group with t-test showed significant differences [p=0.000]. There were not significant differences in respect to analysis of difference of pre-test and post-test scores between groups. Three-dimensional model had positive effect on anatomy learning of middle ear but it didn't cause significant difference in comparison with traditional educational method

[Simultaneous effect of vitamin C and warfarin on coagulation pathways of rats]

The aim of the present study was to assess variations in coagulating pathways after simultaneous administration of warfarin and vitamin C. A total of 50 Wistar rats were selected. The rats were divided into 5 groups[1 group as control and 4 groups as experiment; with 10 rats in each group]. One group was control group, second group was given only warfarin for 10 days while the third group given warfarin and vitamin C simultaneously for 10 days, fourth group was given only warfarin for 20 days, and fifth group was given warfarin and vitamin C simultaneously for 20 days. After 10 th and 20 th days of administration of warfarin and vitamin C, blood samples were taken in order to measure PT, PTT, BT and CT levels. Vitamin C caused a decrease in PT and PTT after 20 days. PT and PTT showed a significant decrease after 10 days in the group that received only warfarin as compared to the group that received warfarin and vitamin C. BT levels showed a decrease after both 10 and 20 days in the group that received warfarin and vitamin C together as compared to the group that received only warfarin. There were significant statistical differences in BT of the two groups of rats [group receiving warfarin and vitamin C and group receiving only warfarin] [P<0.05]. Simultaneous administration of vitamin C and warfarin [20 days] results in decrease of PT, PTT, BT and CT and neutralization of warfarin effect. The effect of vitamin C on blood coagulation can be similar to vitamin K

[Ulcer repair by spray of epithelial stem cells]

Separation, prolifration of stem cells and repairing of injured parts using these cells. This was a Lab-Experimental study. We used 6 male albino rabbits. At first, under general anesthesia 5x5 cm2 full thickness skin from one of the rabbits separated, washed using 70% alcohol and inserted in cold HBSS. Then it was cut into 4-6 mm pieces, washed again and incubated in Tripsin -EDTA 0.1% for 30 minutes at 37C. The cell suspention was then centrifuged and resuspended in DMEM culture. After 10 days the cells separated from the bed using Tripsin method. In experimental group the wounds were sprayed with 2 ml cultured keratinocytes cells and bandaged with vazeline. In control group just the skin was removed and the wounds healed withought cell spray. At the end of 4th week all rats were sacrificed, the repaired regions separated and studied with H and E and tricrom mason staining. In cell studies, the colonies of stem cells were visible using special staining. In Histological studies the epiderm of repaired wounds with cells were normal but the keratoid layers were thiner than normal skin. No sweat gland was observed. Other findings were: shorter finger, nodes, regular collagen fiber in dermal layer and wider vesseles. This method of cell culture would repaire a wide region and obtain a normal skin in a little time

Evaluation of serum and milk amyloid A in some inflammatory diseases of cattle

This study was designed to evaluate serum and milk amyloid A [SAA] as an inflammatory indicator in inflammatory diseases. Twenty clinically healthy cows and 100 cows with various inflammatory diseases were selected for this study. Blood samples were collected from the coccygeal vein of both healthy and diseased groups. Milk samples were taken from four quarters of both groups. Milk samples of four quarters from each cow were mixed, then one sample was taken from pooled milk. There was significant difference in concentrations of serum and milk AA between clinically healthy cows and diseased cows [P<0.05]. The difference of SAA and MAA between cows with subclinical mastitis and other inflammatory disease of cows was also significant [P<0.05]. In conclusion, serum and milk amyloid A are useful diagnostic indicators in the inflammatory diseases of cows

[Comparison between the effect of dexamethasone luntophoresis and drug therapy on 60 cases with carpal tunnel syndrome]

Carpal tunnel syndrome [CTS] is the most common entrapment neuropathy in all peripheral nervous system e of it is one of the most important causes of disability in patients. This study was designed to compare the efficacy of luontophoresis and medical treatment for idiopathic CTS. 60 consecutive patients with CTS confirmed by electromyography participated randomly in two experimental groups [drug therapy], and luontophoresis. lntervention in each group include 20 daily treatment luontophoresis [4ma, positive electrode, 15 mm/session] applied to the area over the carpal tunnel of the wrist region. Measurement were performed before and after treatment and included pain assessment, electromyo and neurography measurement [motor and sensory latency, motor and sensory nerve conduction velocity], grip strength. Improvement was significantly more pronounced in Iuntophoresis group than drug therapy group for variables, motor latency [P<0/000], sensory latency [P< 0/005], hand grip [P<0/000], and pain relief [P<0/000]. In clinical findings atrophy was not observed. Nocturnal pain and paresthesia were reduced 80% in luntophoresis group but 46/6% in control group. Results indicate both luntophoresis and drugs were effective, but luntophoresis was better than drugs. Further investigation is needed to investigate the effects of combination of these treatments in patients with mild to sever CTS
