Background and Aim: Female pattern hair loss(female androgenic alopecia) is a common but puzzling condition in women which increases by aging. Female hair loss is strongly linked to hormones and hormonal imbalances. The aim of this study was to determine the serum level of hormones such as T4, TSH, free testosterone, Prolactin(PRL) and Alb, SHBG in women(15-50 years old) with hair loss versus those without hair loss.

Materials and Methods: In this cross-sectional case-control study, 71 women with hair loss and 70 normal women were selected from skin and hair care day clinics. The level of hormones and SHBG were measured by ELISA, and Alb was measured by spectrophotometery. Data were analyzed by independent t-test.

Results: After analyzing the data and determining the levels of TSH, T4, Prolactin, Alb, SHBG, no significant difference was found between the case and control groups. However, free Testosterone level was significantly different between patients and controls(P= 0.000), with a higher mean level in the case group(patients).

Conclusion : Since androgens have a major role in regulating the biological cycle of hair in women and since there was a significant difference between free testosterone in patient and control groups, we suggest that the serum level of free testosterone should be measured in women with androgenic alopecia .

 Background and Aim: Isoflurane is one of the selective and mostly-used respiratory anesthetic materials in the field of neurosurgery. Studies have shown that temporary rise in the level of liver enzymes may occur after anesthesia by halogenic ethers and hence cause liver lesions. The aim of this study was to investigate the effects of isoflurane on the activity of ALT-AST-ALP-GGT enzymes as an indicator of liver function.

 Materials and Methods: This study was performed on a sample of 40 patients who were under neurosurgery without any liver disease in Milad Hospital of Tehran. The patients' blood samples were collected before, 24, and 72 hours after anesthesia. The enzymes activities was assessed by spectrophotometric method.

 Results: Insignificant changes before and after anesthesia were seen in the activity of ALP, and AST enzymes. The level of ALT enzyme has a significant rise, 72 (P=0/022) and 24 (P=0/014) hours after anesthesia in comparison with before anesthesia. The level of GGT enzyme in comparison to its past has significant rise 72 hours after anesthesia (P=0/002). The level of this enzyme showed a significant difference 24, and 72 hours after anesthesia (P=0/041).

 Conclusion: The significant changes seen in the levels of ALT, GGT enzymes in three different periods of time might be as a result of possible liver parenchymal and cholestatic damage caused by using Isoflurane or other drugs such as Midazolam which effects liver function. It seems the assessment of the levels of these enzymes can provide useful information for probable subsequent actions.
