BACKGROUND: Gravity traction is a widely used conservative procedure, and several studies using various techniques have reported changes in blood pressure (BP) or heart rate (HR) or stress variables in the head-down tilting position, with varying results. The purpose of this study was to investigate BP, HR and serum lactic acid (LA) responses to inverted gravity traction at six angles. METHODS: Thirty volunteers (males 15, females 15) were assigned randomly to either of two experimental groups. After the resting BP, HR and LA concentration were measured in the sitting position, they were measured repeatedly at standing, supine, and inverted at -30, -60 and -90 degrees every 2.5 minute. RESULTS: Compared to the systolic BP (SBP) at sitting, SBP decreased at standing and at inverted -30degrees and increased at -60degrees and -90degrees in the males group, whereas SBP decreased at supine to inverted -60degrees and increased at -90degrees in the females group. Compared to the diastolic BP (DBP) at sitting, DBP diastolic blood pressure (DBP) decreased at standing to -60degrees in both groups and increased at inverted -90degrees. Compared to HR at sitting, HR decreased at supine to -90degrees in both groups. The results of the post hoc test comparisons showed that the SBP, DBP, and HR differed significantly at all six positions. However, compared to serum LA at sitting, LA at all positions were not significantly different in both groups. CONCLUSIONS: As seen in previous research, our results showed increases in BP and HR at inverted -90degrees. However, BP and HR at the other inverted positions including supine showed decreases. LA did not change significantly at any of the positions. Finally, our study showed that angles above -30degrees or -60degrees can benefits the cardiovascular system in young people.

A 22-year-old-male patient has numerous brownish-black, soft follicular papules which compatible with acne are scattered on the chest, scapular regions, back and buttocks for 4 5 years duration. Biopsy specimen revealed cystic structures in the mid-dermis lined by squamous cell epithelium w4ich contained laminated keratinous material and varying number of vellus hairs, histopathologically, compatible with diagnosis of eruptive vellus hair cysts.

As public awareness of the various warning signs of malignancy increases, so does the concern evoked by the self identified finding of mass in the head and neck area. Not all the palpable masses are always significantly abnormal, but any nontender mass especially to the adult is significant enough to warrant further full investigation and follow up, the object of which should be to determine the possibility of malignancy and urgency of treatment. Approach to the diagnosis of the neck mass is so important in that it affects decision regarding further evaluation would lead to the determination of the most efficacious mode of therapy, eventually to the good prognosis. So, it should be emphasized that approach to the diagnosis of neck mass should be planned, systematic and thorough, this begins with the taking careful history following performance of complete examination of the head and neck especially to the nasopharynx, tongue base, pyriform sinus, palatine tonsil and larynx. Then a number of laboratory and radiologic studies are available, following triple endoscopy under general anesthesia and blind biopsy if needed. The most important rule to keep is that any biopsy procedures should be delayed to the last modality of effort to the diagnosis and if it should be done, under the plan of radical neck dissection.

Nasopharyngeal angiofibroma is a relatively rare, but is a well known tumor that occurs almost in male, most frequently during the adolescent stage. Its character is histologically benign but clinically malignant because of locally invasive character to the adjascent structures, massive bleeding tendency during surgical procedure and high recurrence rate after treatment. Recently many advancements diagnostic method and surgical technique has reached satisfactory result in treating this difficult tumor. The authors present a case of nasopharyngeal angiofibroma in 16 years old male patient, who was received surgical removal of the tumor through the transpalatal approach after full diagnostic evaluation and preoperative hormonal therapy.

Modified Mohs surgery is a procedure which eliminated chemical fixation step from Mohs chemosurgery. This technique is faster, less painful and more tissue conserving, allows for immediste repairs, yields higher quality histologic preparations and facilitates an interdisciplinary apporoach; it is the treatment of choice for recurrent or difficult skin cancers. A 58-year-old femele patient presented with a 2x 3cm sized dark brownish, ulcerated nodule on the left upper eyelid. Histopathologic findings revealed several small solid nest composed of basalioma cells in the dermis. We treated with modified Mohs surgery and obtained good result.

BACKGROUND: Intracellular calcium overload is a common final feature of the ischemic-reperfused heart and mediates the genesis of irreversible cell damage. Reactive oxygen medabolites have been known to play and important role as toxic mediators in myocardial injuries resulting from ischemia and reperfusion. In order to investigate the mechanism of intracellular calcium accumulation in the ischemic-reperfused myocardium, the present study observed the possible contribution of the reactive oxygen metabolite to the calcium transport of cardiac mitochondria. METHODS: Mitochondrial were isolated from rabbit hearts. The effects of a reactive oxygen metabolite, H2O2 on calcium uptake and release, redox states of endogenous pyridine nucleotides and glutathiones of mitochondria respiring with succinate were observed. Calcium uptake and release were monitored by dual-wave length spectrophotometer using a calcium indicator, arsenaze III. Contents and redox states of pyridine nucleotides and glutathiones were measured by enzymatic methods using spectrofluorometer and HPLC. RESULTS: Hydrogen peroxide(10-500microM) promoted calcium release dose-dependently from CA++-preloaded mitochondria, but did not affect the mitochondrial calcium uptake. The H2O2-induced calcium release was accompanied by simultaneous oxidation of the pyridine nucleotides and decrease in the content of the reduced form of glutathione(GSH). When mitochondria were treated with BCNU(N,N=bis(2-chloroethyl)-N-nitrosourea) to inhibit glutathione reductase and so as to reduce the GSH content, there were no increase in calcium release from the mitochondria. These results may indicate that H2O2 increases the permeability of cardiac mitochondrial membrane to calcium in association with the changes in redox state of endogenous pyridine nucleotides, but not with that of glutathiones. CONCLUSION: It is suggested that the reactive oxygen metabolites induce the release of calcium from mitochondria by altering the redox state of pyridine nucleotides, and it may partly be involved in the elevation of cytosolic calcium concentration in the ischemic-reperfused myocardial cells.
