Radiotoxicity of gamma rays and radioprotection of antioxidant vitamins against sperm head malformation in irradiated mice

In this study, 140 Swiss albino mice [Mus muscularis] aged 7 weeks and weight 15-20 gm. were used. The animals were sorted into groups, one of them was irradiated with two concentration of gamma rays 300 and 900 rad, other groups were treated with aqueous vitamin C solution; vitamin E solution dissolved in olive oil and both of them together [C and E] at two concentrations, 100 and 500 mg/kg/day for one month, then radiated in two doses 300 and 900 rad. Sperm head abnormalities in non irradiated; irradiated and pretreated with vitamins groups then irradiated were recorded. The irradiation with 300 and 900 rad caused an increase in the sperm head abnormalities compared to the control. On the other hand, animals pretreated with vitamins each alone and combination of the two together showed a decrease in the percentage of abnormalities caused by irradiation. So, vitamin C and vitamin E [antioxidant] were considered as radioprotection

One stage lumbar spinal osteotomy in ankylosing spondylitis with immediate correction and fixation with two narrow dynamic compression plates and pedicular screws

Six patients with flexion deformity of the spine due to ankylosing spondylitis were treated with a one stage spinal osteotomy through the lumbar spine. All patients were males. The average age was 25.33 +/- 2.16 years. The average pre-operative degree of deformity was 38 +/- 3.58 degrees. The deformity was corrected at the time of the surgery and the osteotomy was fixed internally with two dynamic compression platesand pedicular screws. The average correction angle was 32.83 +/- 2.32 degrees and the average time to union was 4.17 +/- 1.17. No neurological deterioration or aortic rupture occurred in any of the patients

Assessment of patellar alignment in normal subject

Patellar malalignment problems have long been recognized as a cause of dysfunction at the knee. The patellar malalignment syndrome is a condition that presents with clinical symptoms such as popping, giving way, effusion, buckling, weakness, patellar subluxation, and pain with certain activities. Realignment of the patella through conservative technique has become the main emphasis of treatment. Due to this emphasis on patellar realignment, a need for a quantitative measurement of patellar orientation has developed. The purpose of this study is to assess the normal patellar position by measuring the Q-angle, patellar height and patellofemoral congruence, using an X-ray techniques which was implemented for this purpose, and to compare these parameters in patients with patellofemoral joint dysfunction
