2.Influence of Thyroid Status on Serum Levels of Leptin and Leptin mRNA in Rats
Journal of Applied Clinical Pediatrics 1994;0(04):-
Objective To explore the influence of thyroid status on serum level of leptin and expression of leptin mRNA in rats with hypothyroidism or hyperthyroidism.Methods Fifty rats were artificially rendered hyperthyroidism and hypothyroidism by L-thyroxine or methimazole and divided into 5 groups.The serum of T 3,T 4,TSH,leptin concentration and expression of leptin mRNA were measured in 5 groups.Results Serum leptin concentration was significantly correlated with weight of rats in 5 groups(P

Objective To study the effects of calcitonin on bone mineral density(BMD), bone strength and bone fragile fracture in osteoporosis. Methods This is a one year, single centered, prospective and randomized, opening study: 135 patients with osteoporosis were divided into calcitonin+calcium group and calcium group. Patients of calcitonin+calcium group received salmon calcitonin(Miacalcic was injected intramuscularly, 50 IU/day in first week, 50 IU/two days in second week and 50 IU/twice/week later) and calcium(calcium 600 mg/day), patients in another group received calcium(calcium 600 mg/day). The determination markers included serum calcium, serum phosphate, serum alkline phosphatase, osteocalcin and urine hydroxyproline before and after treatment, at same time all patients were examined by DEXA(lumbar, hip) and QUS(radius, tibia). Results After 1 year treatment, 53 patients of calcitonin+calcium group and 59 patients of calcium group were followed up. In calcitonin+calcium group, BMD of lumbar spine increased about 1%(P

Objective To investigate the changes of serum interleukin 8(IL-8) level in children with thyroid disfunction and its clinical significance in children with autoimmune thyroid disease(AITD).Method Serum IL-8 of 30 children with hyperthyroidism,16 children with hypotyroidism and 20 health children were detected by double antibody enzyme linked immunossorbent assay(ELISA).Results Serum IL-8 levels in hyperthyroidism and hypothyroidism children were significantly higher than that in controls(P0.05).With the remission of the diseases, IL-8 levels decreased; there was a significant difference between serum IL-8 levels in patients before and after therapy (P

Although the type of XHD150B-IO 800mA X-ray machine possesses a damage protection electric circuit for the main thyristors, with the first switch of photographic hand valve pressed, abnormal instant exposure still appears when double (in different phase) or more than three main thyristors are broken through, short-circuited or mis-energized, and consequently the high voltage element or X-ray machine will break down. Therefore the original electric circuit must be improved. Material: A few of leads. Method: We exchange the conjunction sequence of three NO (normal open) contacting points of radiograph high voltage preparing work relay--MAG SW- R with three reverse parallel connection of main thyristors. Conclusion: The normal procedure of radiographic exposure won't be disturbed after the improvement. When whichever one or more than two main thyristors is broken through, short-circuited or mis-energized, the spoilage can be detected instantly and the protection circuit works correspondingly, which guarantees the safety of X-ray machine.

Objective To observe the effect of electroacupuncture(EA) on the angiogenesis in rats with cerebral ischemia.Methods 30 male Wistar rats were randomly divided into 3 groups:normal group,model group and EA group.After the establishment of acute middle cerebral artery occlusion(MCAO),the rats were treated with EA on DU20 and DU26.Then the expression of bFGF,Ang-2 and Tie-2 by immunohistochemical staining was ob- served.Results The expression of bFGF and Ang-2 around the infarction locus of EA group increased remarkably compared with normal group and model group and the increase of Tie-2 was not significant.Conclusion EA can increase the expression of bFGF and Ang-2 around the infarction locus and promote the angiogenesis in rats with cere- bral ischemia.

The mRNA levels of adiponectin in adipose tissue and adiponectin receptor R1 in skeletal muscle of type 2 diabetic rats were examined by semi-quatitative RT-PCR.The expression of adiponectin receptor R1 was not altered in the skeletal muscle of type 2 diabetic rats as compared with normal rats.The serum adiponectin level was decreased in diabetic rats due to the decline of adiponectin mRNA level in adipose tissue and rosiglitazone improved the adiponectin deficiency.
