An 84-year-old woman had an ovoid shallow ulcer with an elevated, indurated, pigmented border on the left cheek. Histological examination revealed a moderately differentiated squamous cell carcinoma and a solar keratosis with abundant melanocytes and melanin pigment. Ultrastructurally, the keratinocytes contained numerous melanosomes in their cytoplasms and the melanocytes in the squamous cell carcinoma and the solar keratosis had mature melanosomes.

A delayed hemolytic transfusion reaction (DHTR) is the result of delayed anamnestic alloantibody response four to fourteen days after transfusion of apparently compatible blood. Most DHTRs are very mild and may not be recognized clinically. Some are manifested only by anemia. Only a few cases are severe enough to induce a massive hemolytic reaction followed by frank renal failure. Recently, we experienced a case of DHTR with acute renal failure (ARF) due to anti-E. A 21-year-old woman received compatible four units of packed red cells after right artificial total hip replacement arthroplasty due to juvenile rheumatoid arthritis. She had a history of transfusion 4 years ago. Fourteen days after the transfusion, she showed a fall in hematocrit, hemoglobinuria and a positive indirect antiglobulin test, and accompanied by ARF. Anti-E was identified in the patient's serum by antibody screening and identification test at that time. She recovered from ARF after hemodialysis with conservative management. However, eventually, she died due to disseminated intravascular coagulopathy.

OBJECTIVE: To evaluate the difference of implantation rate (IR) and clinical pregnancy rate (CPR) between two protocols of endometrial preperation in women undergoing frozen-thawed embryo transfer (FET) cycles. METHODS: This study was performed during the different time periods: A retrospective study from January 2000 to June 2001 (phase I) and a prospective study from July 2001 to March 2002 (phase II). All the patients received estradiol valerate (6 mg p.o. daily) starting from day 1 or 2 of the menstrual cycle without pituitary down regulation. Progesterone was administered around day 14 after sonographic confirmation of endometrial thickness > or = 7 mm and no growing follicle. In Group A (n=88, 99 cycles) of phase I, progesterone was administered i.m. at a dose of 50 mg daily from one day prior to thawing of pronuclear (PN) stage frozen embryo or three days prior to thawing of 6-8 cell stage frozen embryo and then each stage embryos were trasnsferred 2 days or 1 day later after thawing. In Group B (n=246, 299 cycles) of phase I, patients recieved progesterone 100 mg i.m. from one day earlier than group A; two days prior to PN embryo thawing, four days prior to of 6-8 cell embryo thawing. During the phase II, to exclude any differences in embryo transfer procedures, in Group 1 (n=23, 28 cycles) of phase II embryo was transfered by one who have used the progesterone protocol since the phase I. In Group 2 (n=122, 139 cycles) of phase II embryo was transfered by one who use the progesterone protocol from the phase II. RESULTS: When compared across the phase and group, there were no significant differences in the characteristics. During the phase I, there were significant increase in IR (14.4% vs 5.9%, p=0.001) and CPR (28.3% vs 14.5%, p=0.000) in group A. During the phases II, IR (11.8% vs 10.6%) and CPR (27.6% vs 27.3%) show no differences between two groups. CONCLUSIONS: In FET cycles, IR and CPR are increased significantly by the change of dosage and timing of progesterone administraton. And the timing is considered to be more important factor because the dosage of progesterone did not affect implantation window in previous studies. Therefore, we suggest that progesterone administration in FET cycle should begin from one day prior to PN stage embryo thawing and three days prior to 6-8 cell stage embryo thawing.

OBJECTIVE: A dichotomous Thl and Th2 cytokine profile has been associated with reproductive failure and success, respectively. The purpose of our study was to determine the levels of Thl cytokine (IFN- y ) secreted by peripheral blood mononuclear cells (PBMCs) form women with unexplained recurrentabortion (URA) and fertile controls in response to trophoblast antigen. METHODS: PBMCs were isolated from 30 nonpregnant women with URA and from 10 nonpregnant fertile controls. Following 4 days of culture (1 * 10(6) cells/mL) with and without a protein extract derived from a trophoblast cell line (30 ug/mL, protein). None of the women had allergies, atopy or recent infection. Cytokines were measured in supernatants with enzyme-linked immunosorbent assay (ELISA) kits. IFN- r kit was obtained from BOISOURCE (lower limit of sensitivity, 15.6 pg/mL for IFN- r ). All values below the lowest limit of sensitivity as determined by test kit standards were considered negative. The cytokine stimulation test is considered positive if the IFN- r concentration increases by 200% or more with the trophoblast antigen stimulation. Datas are presented as mean+ SEM. Nonparametric testing (Mann-Whitney U) was used for analysis with P<0.05 considered statistically significant. RESULTS: The Thl-type cytokine (IFN- r ) was detected in 20(67%) of 30 supernatants from women with URA. In contrast, 2 (20%) of trophoblast-activated PBMC culture supernatants from the 10 parus women with normal reproductive histories was detected IFN- r and but were significantly lower than levels in women with URA who had secreted IFN- r upon trophoblast stimulation (99.80+ 18.17 pg/mL versus 166.47 + 36.96 pg/mL, p<0.05). Spontaneous secretion of IFN- r was significantly higher in culture supernatants from women with URA than in supernatants from women with successful reproductive histories (41.36.09+6.99 pg/mL versus 25.89+9.34 pg/mL, p<0.05). CONCLUSION: These data indicate that there are significant differences between women with URA and women with normal reproductive histories in their regulation of the Thl-cytokine (IFN- r) in response to trophoblast. Thl-type immunity to trophoblast is associated with URA and may play a role in reproductive failure.

PURPOSE: Febrile convulsions are a common pediatric neurological disease, and it is important to prevent such a disease by controlling the risk factors that may recur. A recent report states that influenza virus infections have a high probability of a relationship with febrile convulsions; therefore, it is necessary to identify the clinical properties of febrile convulsions in relation to domestic influenza virus infections. METHODS: Between November 2005 and February 2008, children hospitalized because of febrile convulsions and subsequently confirmed to have influenza infections were enrolled as subjects (patient group, n=11). The control subjects were those admitted with influenza virus infections but no febrile convulsions (control group 1, n=46) and those who developed febrile convulsions without influenza virus infection (control group 2, n=53). RESULTS: The patient group showed a higher maximum body temperature (39.3+/-0.5degrees C), more histories of past febrile convulsions (72.7%), and a shorter total duration of fever (2.9+/-1.2 days) than control group 1. When multivariate analysis was performed, the probability of febrile convulsions was found to be as high as 225.9 times in patients who had influenza virus infections with a past history of febrile convulsions (OR=225.9, 95% CI: 1.7-4780.0, P<0.05). When patients with febrile convulsions were compared based on the symptoms of influenza virus infections, the patient group showed a shorter duration of fever (0.9+/-0.7 days) before convulsion than control group 2; these convulsions were mostly a recurrence of febrile convulsions. When multivariate analysis was performed, the cases with a past history of febrile convulsions showed 5.5 times (OR=5.5, 95% CI: 1.2-25.1, P=0.03) the probability of convulsions when infected with the influenza virus, and this probabilit. decreased by 0.3 times over one-day increments of the febrile period until febrile convulsions (95% CI: 0.1-0.9, P=0.02). Maximum body temperature, total duration of fever, family history of febrile convulsions, and complex febrile convulsions did not show a statistical significance. CONCLUSION: In cases of pediatric influenza virus infection, the past history of febrile convulsions could be identified within the risk factor of recurrent febrile convulsions. Therefore, influenza vaccination of children having a past history of febrile convulsions will be helpful to avoid the recurrence of these convulsions.

The salivary glands produce 1.5L of fluid per day. As in other exocrine organs, the general mechanism in the salivary glands is that water movement occurs secondary to osmotic driving forces created by active salt transport. Therefore, high water permeability in the salivary glands is expected to have a variety of aquaporin (AQP), a water channel. Although some AQPs have been known to be present in the salivary glands, roles of parasympathetic nerve in AQP expression have not yet been examined. This study was designed to examine the changes of AQPs and extracellular signal-regulated kinase (ERK) in the submandibular glands after parasympathetic denervation. Right chorda-lingual nerve was cut, and each right (experiment) and left (control) submandibular gland was excised at 1, 3, 7, 14, 30 days after denervation. The denervated right submandibular glands were resulted in weight loss and morphologic changes, including cell loss and atrophy, as the time elapsed after parasympathetic denervation increased, whereas there were no histologic alteration in control side. AQP5 which is known to reside in apical membrane and secretory caraliculi of the submandibular acini were gradually underexpressed according, as the time after denervation increased. Expression of AQP4 in submandibular ductal epithelium was down-regulated after denervation. Besides, AQP3 and 8, which is known to be present in basolateral membrane of the glandular acini, were gradually underexpressed after denervation, similar to the pattern of other types. Expression of ERK, a mitogen-activated protein kinase, was downregulated after parasympathetic denervation in the submandibular gland. These results suggest that parasympathetic nervous system regulates the expression of AQPs in salivary glands, and is in part mediated by ERK pathway.

OBJECTIVE: To estimate the efficacy of recombinant human follicle stimulating hormone (rFSH) versus highly purified urinary human FSH (uFSH) in women undergoing controlled ovarian hyperstimulation (COH) for in vitro fertilization and embryo transfer (IVF-ET). METHODS: From 1 January 2001 to 31 August 2001, A total of 254 cycles from 241 patients who attended infertility clinic at Samsung cheil hospital was enrolled in this study. With pituitary down regulation using GnRH agonist by short protocol, rFSH (Puregon(R), Organon, Netherlands) was administered in 131 cycles and uFSH (Metrodin-HP(R), Serono, Switzerland) was administered in 123 cycles. We analyzed ovarian response, pregnancy rate, live birth rate, oocyte quality and embryo quality. RESULTS: The clinical characteristics of two groups were not different. Total FSH dosages (1322.3+/-526.2 IU versus 2124.4+/-881.9 IU, p<0.001) and dosages per retrieved oocyte (90.6+/-36.0 IU versus 138.0+/-57.2 IU, p<0.001) were significantly lower in rFSH group than uFSH group. Clinical pregnancy rate and live birth rate of two groups were not significantly different. The rate of good quality oocyte (Grade I and II) from retrieved oocytes was higher in rFSH group (68.2% versus 64.8%, p=0.024), but after preincubating oocytes for 4 to 6 hours and removing cumulus cells in intracytoplasmic sperm injection (ICSI) cycles, nuclear maturity of oocytes were not significantly different. The quality of transferred embryos were not significantly different too. CONCLUSION: rFSH offered more effective ovarian response in COH and better quality of retrieved oocytes, compared with uFSH.

BACKGROUND/AIMS: This study was designed to determine the effect of hepatic fibrotic severity on pharmacokinetics of propranolol in CCl4-treated rats. METHODS: 1 mL/kg of 10% CCl4 in olive oil was injected intramuscularly to rats twice weekly for 4, 6, 8 and 10 weeks, respectively (n=6). Control (n=6) was a sham-injected equal dose of olive oil for 10 weeks. After intravenous bolus injection of 2 mg/kg propranolol to rats, the serum propranolol concentrations were analyzed for 4 hours at various time points by a HPLC-fluorimetric system, and pharmacokinetic parameters such as C0, MRT, AUC, Vdss, t1/2( ) and CLp were determined. Then, a small amount of hepatic tissue was obtained and subjected to determination of the hepatic 4-hydroxyproline content, which confirmed the hepatic fibrotic severity. RESULTS: The serum concentrations of propranolol at 0.5, 1, 2 and 4 hours were significantly increased in CCl4-treated rats (p<0.01). In proportion to the duration of CCl4 treatment, C0 and AUC were significantly increased, and Vdss and CLp were significantly decreased (p<0.001). But MRT and t1/2( ) were not significantly changed. The hepatic 4-hydroxyproline content was gradually increased in CCl4-treated rats (p<0.001). CONCLUSION: Gradual changes in pharmacokinetic parameters of propranolol were seen to be dependent on the hepatic fibrotic severity. We suggest that gradual dosage modification, according to their hepatic fibrotic severity, is necessary for many drugs administered to patients with chronic liver disease.
