Objective : This study investigated the effects of Yangsaengwhallyukdan on nitrite oxide synthase (NOS) activity, nitrite level, antioxidation and erectile response in rat corpus cavernosum penis. Methods : Yangsaengwhallyukdan was formulated to contain various natural products that have been used to treat erectile dysfunction. Yangsaengwhallyukdan suspended in a 0.5% CMC solution was oral-administered, 50 mg or 100 mg per 1 kg of body weight for 30 days, while the normal group was administered only with a 0.5% CMC solution. The efficacy of the Yangsaengwhallyukdan was assessed with regard to erectile function. Results: After the Yangsaengwhallyukdan was administered to the rat for 30 days, the urethral NOS activity increased. The level of urethral nitrite, glutathione and testosterone increased too. The level of urethral lipid peroxide was decreased in Yangsaengwhallyukdan treated rats. The erectile response to a cavernous nerve stimulation in L-NAME$(10^4)$-treated rats in rats given Yangsaengwhallyukdan reached the level of the normal group. Conclusions : This study suggest that Yangsaengwhallyukdan is effective for the treatment of erectile dysfunction.

Ethanol extract of 20 botanicals in 3 concentrations i.e., 2.5%, 5% and 10% were evaluated for their efficacy to improve reproductive performance of mulberry silkworm (Bombyx mod L.) through feeding botanical enriched mulberry leaves during $2^{nd}$ day of $4^{th}$ age as well as $1^{st}$ and $3^{rd}$ day of $5^{th}$ age larvae. The preliminary screening was done by ranking the botanicals based on influence in most important reproductive contributing parameters such as single cocoon weight, effective rate of rearing, pupation rate, fecundity and recovery of eggs/kg cocoon. Five botanicals viz., Asparagus recemosus, Achyranthes aspera, Tribulus terrestris, Withania somnifera, Parthenium histerophorus ranked first were further evaluated at 8% 5% and 3% concentrations to confirm their effectiveness and standardize effective concentration. Among the rearing parameters, mature larval weight, shell ratio and number of cocoons/kg were not significantly influenced by the treatments. However, reproductive parameters such as effective rate of rearing (wt), pupation rate (%), fecundity (No.) and egg recovery (g)/kg cocoon were significantly (P<0.05) influenced by the botanicals. Higher fecundity and egg recovery were obtained on treatment with Withania somnifera irrespective of concentrations. However at 5% concentration, pupation rate, fecundity as well as egg recovery were found significantly higher than that of other concentrations, confirming its effectiveness for improving reproductive efficiency.

Neutropenia is a major dose-limiting side effect of cancer chemotherapy. The therapeutic effect of HM 10411 was examined on neutropenia caused by anticancer agents. Neutropenia in normal ICR mice was induced by a single combined intraperitoneal injection of 130 mg/kg of cyclophosphamide (CPA). 4.5 mg/kg of doxorubicin (DXR). and 1 mg/kg of vincristine (VCR) on day O. Neutropenia in tumor-bearing mice was made by a single intraperitoneal injection of 200 mg/kg of cyclophosphamide (CPA) into BALB/c mice bearing Colon 26 adenocarcinoma at 7 day after tumor implantation. HM 10411 or filgrastim (100 $\mu\textrm{g}$/kg/day) was subcutaneously administered for 5 consecutive days starting 1 day after injection of anticancer agents in order to stimulate neutrophil production. Injection of HM 10411 accelerated the recovery from these anticancer drug-induced neutropenia. In normal and tumor-bearing mice. neutrophil production efficacy of HM 10411 was similar than that of filgrastim. These results suggest that HM 10411 could be useful in the clinical treatment for neutropenia induced by anticancer agents.

Purpose: The purpose of this pilot study was to investigate a potential of platelet concentrate obtained from blood bank(PCBB) in accelerating wound healing and to determine an effective treatment protocol by quantifying levels of platelet derived growth factor (PDGF)-BB in PCBB in vitro. Methods: The first study was designed to investigate quantity of PDGF-BB over stored time of the PCBB. The stored times for each PCBB were 1, 3, 5, 7, 9, 11 and 13 days. The second study was designed to determine efficacy of adding thrombin to stimulate release of PDGF-BB from the platelets of PCBB. The platelets were suspended and incubated in either with or without thrombin. On 30 minutes and days 1, 3, 5, 7 after incubation, the levels of PDGF-BB were measured. Results: PDGF-BB level showed a linear decrease over stored time of PCBB from the first day to the 13th day. Addition of thrombin increased PDGF-BB release from 30 minute through the 5th day. Conclusion: The results indicate that PCBB can provide sufficient amount of growth factors to stimulate wound healing and adding thrombin accelerate it.

Previous observations demonstrated that various immunosuppressive agents and their combination therapies can increase allograft survival rates. However, these treatments may have serious side effects and cannot substantially improve or prolong graft survival in acute graft-versus-host disease (GVHD). To improve the therapeutic potency of divalent immunoadhesins, we have constructed and produced several tetravalent forms of immunoadhesins comprising each of cytotoxic T-lymphocyte-associated antigen-4 (CTLA4), CD2, and lymphocyte activation gene-3 (LAG3). Flow cytometric and T cell proliferation analyses displayed that tetravalent immunoadhesins have a higher binding affinity and more potent efficacy than divalent immunoadhesins. Although all tetravalent immunoadhesins possess better efficacies, tetravalent forms of CTLA4-Ig and LAG3-Ig revealed higher inhibitory effects on T cell proliferation than tetravalent forms of TNFR2-Ig and CD2-Ig. In vitro mixed lymphocytes reaction (MLR) showed that combined treatment with tetravalent CTLA4-Ig and tetravalent LAG3-Ig was highly effective for inhibiting T cell proliferation in both human and murine allogeneic stimulation. In addition, both single tetravalent-form and combination treatments can prevent the lethality of murine acute GVHD. The results of this study demonstrated that co-blockade of the major histocompatibility complex class (MHC)II:T cell receptor (TCR) and CD28:B7 pathways by using tetravalent human LAG3-Ig and CTLA4-Ig synergistically prevented murine acute GVHD.

Background: Pain due to spinal stenosis is one of the major causes of low back pain, and it sometimes does not respond to conservative treatment. We postulated that anterior epidural irrigation could be a good choice for treating lumbar spinal stenosis patients. However, the effects and theoretical basis of anterior epidural irrigation have not been investigated for spinal stenosis. So, this study was designed to identify the clinical efficacy of anterior epidural irrigation for treating lumbar spinal stenosis. Methods: 71 patients with lumbar spinal stenosis underwent anterior epidural irrigation. Anterior epidural irrigation was performed with normal saline and a mixture of local anesthetic with steroid through a catheter under fluoroscopic guidance. The findings were evaluated with using visual analogue scales for low back pain and leg symptoms. Results: Relief from low back pain and leg pain was observed for up to 12 months after anterior epidural irrigation. None of the patients showed any deterioration of their motor or sensory deficits during follow up. Conclusions: Anterior epidural irrigation is effective for the relief of back and leg pain in spinal stenosis patients.

Bacteria from the genus Lactobacillus are important for the production of fermented food and dairy products, and as symbionts in human and animals. Lactobacillus acidophilus has widely been used in the production of yogurt, health foods, and even medicines. The efficacy of L. acidophilus has been proven with regards to the reduction of cholesterol, prevention and treatment of diarrhea, modulation of the immune system, suppression of cancer, etc. Using molecular biology tools, Lactobacillus acidophilus has now been reclassified into six species: L. acidophilus, L. amylovorus, L. crispatus, L gallinarium, L. gasseri, and L. johnsonii. Thus, since L. acidophilus has now been marked as a newly defined species, caution is advised when reading future publications regarding this bacterium. In this article, the results of the reclassification of L. acidophilus are mentioned after an analysis of its field inheritance was performed by my research team. Especially, L. amylovorus KU4 (formerly named as L. acidophilus KU4; KCCM 10975P) is a novel probiotic strain that is isolated from humans; it has the ability to reduce cholesterol. It has also been reported as a microorganism that effectively inhibits the growth of pathogenic E. coli. However, this Korean patent (No 10-1541280) refers to a strain obtained from calves; the origin of this strain was incorrectly labeled. Furthermore, after the discovery of L. acidophilus in 1900, its role in intestinal microbiological research was described and its utilization as a probiotic was presented.

The Epidural blood patch is considered the gold standard for managing postdural puncture headache when supportive measures fail. However, it is a procedure which can lead to another inadvertent dural puncture. Other potential adverse events that could occur during a blood patch are meningitis, neurological deficits, and unconsciousness. The bilateral greater occipital nerve block has been used for treating chronic headaches in patients with PDPH with a single injection. This minimally invasive, simple procedure can be considered for patients early, along with other supportive treatment, and an epidural blood patch can be avoided.

Background: Single pegylated liposomal doxorubicin (PLD) is commonly used as a salvage treatment in platinum-resistant ovarian cancer, fallopian tube cancer and primary peritoneal adenocarcinoma (PPA) with a satisfactory outcome. However, the data for second generation PLD administered in this setting are still limited. We conducted a retrospective study to evaluate the outcome of patients who received single-agent second generation PLD (LIPO-DOX) after the development of clinical platinum resistance. The study period was between March 2008 and March 2013. LIPO-DOX was administered intravenously 40 $mg/m^2$ every 28 days until disease progression, but for not more than six cycles. The response rate was evaluated using the Gynecologic Cancer Intergroup (GCIG) criteria while the toxicity was evaluated according to WHO criteria. Twenty-nine patients met the inclusion criteria in the study period with an overall response rate of 13.8%. The median progression free survival and overall survival were three and eleven months, respectively. With the total of 96 cycles of chemotherapy, the patients developed grades 3 and 4 hematologic toxicity as follows: anemia, 0%, leukopenia, 9.6%, neutropenia, 32.3% and thrombocytopenia, 0%. In conclusion, the single agent second generation PLD demonstrated modest efficacy in patients with platinum-resistant ovarian cancer, fallopian tube cancer and PPA without serious toxicity.
