1.Sustainable Rates of Sebum Excretion in Relation to Menstrual Cycle.
Korean Journal of Dermatology 1988;26(6):791-796
Sustainable rates of sebum excretion(SRSE) was measured in seven women who had normal regular periods, none were taking oral contraceptives with no significant signs of acne or hirsutism, with assays for testosterone, dihydrotestosterone, dehydroepiandrosterone sulfate, and progesterone during menstrual cycle. The SRSE in omen during the follicular phase wa lower in the luteal phase (p <0.01)than in the men (p <0.01). However during the luteal phase the SRSE in the women was increased similar to the SESE in the men. We investigated the above horrnoies in relationship to the SRSE during the women's menstrua] cycle. During the follicular phase the hormone which was the most determining factor affected the SRSl was total testerone, while dihydrotestosterone was the most determining factor of the horrnone affecting the SRSE during the ovulation and luteal phase.

A 22 year old male with hemophilia B was scheduled for the correction of a right subtrochanteric femur fracture. Plasma concentration of coagulation factor IX in this patient was 50% of the normal level and the partial thromboplastin time was 57 seconds on the first day of hospital administration. We started the intravenous administration of facnyne injection (factor IX) 11 days before the operation when his plasma concentration was 20%. His plasma concentration was 40% on the operation day. The operation and general anesthesia were accomplished safely without severe hemorrhage or major complication. He received facnyne injection continuously until the 5th postoperative day: 25-43% of his plasma concentrations of factor IX was maintained. He had no problem with postoperative care.

Flow cytometry, a useful tool for measuring DNA content and cell differentiation as expressed by cell surface markers, is utilized to measure multiple antigens, especially surface antigen, intracellular oncoprotein, and DNA content, simultaneously. For this simultaneous detection, several methods off ixation and permeabilization have been used with limited values. In this study, 20 ng/ml of lysolecithin in 1% paraformaldehyde solution was utilized for fixation and permeabilization of cultured promyelocytic leukemic cells(HL 60). The cells were first stained with phycoerythrin (PE)-conjugated monoclonal antibody to the cell surface My 7 antigen and then were fixed and permeabilized with 20 ng/ml of lysolecithin in 1% partormaldehyde solution. After incubation, the fixed and permeabilized cells were stained with monoclonal antibody to intracellular c-myc antigen, which were followed by fluorescein isothiocyanate (FITC)-conjugated secondary antibody. The c-myc stained cells were finally stained for DNA content with 7-amino-actinomycin D(7-AAD). This procedure permits excellent staining for intracellular oncoproteins and preservation of surface antigens with relatively low cofficients of variation (CV) for the G0G1 peak of the DNA histograms and suggests that the sequential staining procedure of surface antigen, intracellular antigen, and DNA content will be extended for the study of correlations with cellular differentiation, expression of oncoproteins, and cell cycle analysis in the cells which are obtained from human malignant diseases using a 488 nm single laser flow cytometry.

PURPOSE: Receptor activator of nuclear factor-kappa B ligand (RANKL), osteoprotegerin (OPG) have been shown to be important regulators of osteoclastogenesis during bone remodeling, and their expressions were examined during fracture healing in a mouse model of tibial fracture. However, studies linking RANKL and OPG in patients with head injury and fracture are lacking. We evaluated the changes in serum levels of RANKL and OPG in patients with head injury and fracture (head injury group) and in patients with fracture (fracture group) and compared these with levels found in healthy control subjects. MATERIALS AND METHODS: 18 male patients of head injury and fracture and 20 male patients of fracture alone were enrolled. 20 healthy men were recruited to serve as controls. Within the first few hours of admission to hospital, at 4, 8 and 12 weeks after injury 20 ml of blood were obtained from 18 patients with head injury and fracture and 20 patients with fracture only. RESULTS: RANKL levels were significantly lower in the head injury group than in the fracture group at 8 and 12 weeks after injury. OPG levels were significantly higher in the head injury group than in the fracture group at 4, 8 and 12 weeks after injury. RANKL/OPG ratios were significantly lower in the head injury group than in the controls immediately after and 4, 8 and 12 weeks after injury, and were significantly lower in the head injury group than in the fracture group at 8 and 12 weeks after injury. CONCLUSION: We have shown changes in the profiles of RANKL, OPG and RANKL to OPG ratio. The altered RANKL, OPG and RANKL/OPG ratio in the head injury group lasted longer than in those of the fracture group.

BACKGROUND: Ropivacaine and levobupivacaine, both single S-enantiomers, show less toxicity on the central nervous and cardiovascular system than racemic bupivacaine. Earlier studies have shown that levobupivacaine and bupivacaine are almost equipotent while ropivaciane was 60% less potent than bupivacaine. The aim of this prospective, double blinded study was to compare the clinical efficacy and safety of epidural anesthesia produced by 0.5% levobupivacaine and 0.5% ropivacaine for a cesarean section. METHODS: Sixty-two parturients undergoing an elective cesarean section were randomized to receive either epidural levobupivacaine 0.5% 20 ml (n = 31) or epidural ropivacaine 0.5% 20 ml (n = 31). Surgery was commenced when the sensory block had reached the dermatome level, T6. The onset, duration, quality of the sensory and motor block and abdominal muscle relaxation were evaluated. The blood pressure and heart rate of the mother and neonatal outcome, as assessed by the Apgar score and umbilical pH, were also recorded. RESULTS: There was no difference in the onset time, the segmental spread of sensory block and analgesic supplement between the two groups. However, levobupivacaine produced a longer duration of sensory block than ropivacaine (levobupivacaine 224.1 +/- 66.6 min, ropivacaine 176.5 +/- 32.8 min, P < 0.05). The onset time (except Bromage scale 2), intensity and duration of the motor block and muscle relaxation were similar in both groups. There was no difference in the maternal and neonatal outcomes between the two groups. CONCLUSIONS: 0.5% levobupivacaine and 0.5% ropivacaine produced equivalent efficacy and safety in epidural anesthesia for a cesarean section, but levobupivacaine resulted in a longer duration of sensory block.

Several attempts have been made to correlate nasal obstruction and acoustic rhinometric parameters, so far failed to find any significant correlation. We evaluated the correlation between the sense of nasal obstruction and parameters measured with acoustic rhinometry, and searched any secondary variables calculated from primary parameters, to explain the sense of nasal obstruction objectively on 114 patients (72 men and 42 women) with nasal obstruction. The sense of nasal obstruction was measured with visual analogue scale. Nasal volume, minimal cross-sectional area, and equivalent resistance were measured by acoustic rhinometry. As secondary variables, we introduced the concept of decongestion rate which representing the amount of change in the parameters after application of nasal decongestant. Weak correlations were found between the sense of nasal obstruction and total minimal cross-sectional area. Significant correlations were found between the sense of nasal obstruction and decongestion rate of total nasal volume, and particularly in the wider cavity. Stronger correlations than in total population were found in male patients. The decongestion rate may have potential implication in explaining the sense of nasal obstruction.

Twin-twin transfusion syndrome(TTTS) is a serious complication of monozygotic mu-ltiple pregnancy. TTTS is associated with high perinatal mortality rate. The acute form has been attributed to rapid transfer of blood through superficial artery-to-artery or vein-to- vein anastomoses during labor and delivery, resulting in a hypovolemic, anemic donor twin and a hypervolemic, plethoric recipient twin of similar birth weight. The authors present a case of acute twin-twin transfusion syndrome with a review of literature.
