Objectives: This study was performed to analyze the toxicity of the test substance, anti-inflammatory pharmacopuncture (AIP), when used as a single intramuscular-dose in 6-week-old, male and female Sprague-Dawley rats and to find the lethal dose. Methods: The experiment was conducted at Biotoxtech according to Good Laboratory Practices. Twenty (20) female and 20 male Spague-Dawley rats were divided into 4 groups of five 5 female and 5 male animals per group. The rats in the three experimental groups received single intramuscular injections with 0.1-$m{\ell}$, 0.5-$m{\ell}$ and 1.0-$m{\ell}$/animal doses of AIP, Groups 2, 3, and 4, respectively, and the control group, Group 1, received a single intramuscular injection with a 1.0-$m{\ell}$ dose of normal saline. Clinical signs were observed and body weight measurements were carried out for 14 days following the injections. At the end of the observation period, hematology, clinical chemistry, histopathological tests and necropsy were performed on the injected parts. Results: No deaths occurred in any of the groups. Also, histopathological tests showed that AIP had no effect on the injected parts in terms of clinical signs, body weight, hematology, clinical chemistry, and necropsy. Conclusions: As a result of single intramuscular-dose tests of the test substance AIP in 4 groups of rats, the lethal dose for both males and females exceeded $1.0m{\ell}$/animal. Therefore, AIP is a relatively safe pharmacopuncture that can be used for treatment, but further studies should be performed.

Purpose: The purpose of this study was to evaluate the role of mast cell and histamine as typical product of mast cell in ischemia-reperfusion injury of muscle flap using H2 receptor blocker and mast cell stabilizer. Methods: Thirty-five Sprague-Dawley rats weighing 250-300 gm were divided into four groups; Group I: Control group without ischemia, Group II: Normal saline injection group with ischemia, Group III: Cimetidine injection group with ischemia, Group IV: Sodium cromoglycate injection group with ischemia. Well established single pedicled transverse rectus abdominis musculocutaneous(TRAM) flap was designed in all rats and were rendered ischemia by clamping the artery for 150 minutes. All injections were applied intramuscular around gluteal area 30 minutes before reperfusion. The flap survival was evaluated at 7 days after operation. Neutrophil counts and mast cell counts were evaluated 24 hours after reperfusion. Results: The difference of skin flap survival between control group and cimetidine injection group was not significant. In the normal saline injection group flap survival was markedly decreased compared to that of control group. The muscle flap survival was similar to the results of skin flap survival. The neutrophil counts were significantly decreased in control group and sodium cromoglycate injection group than normal saline injection group. The mast cell counts were significantly decreased in cimetidine injection group and control group than both normal saline injection and sodium cromoglycate injection groups. The protective effect of sodium cromoglycate was not seen in the skin flap, but the muscle flaps showed protective effects of sodium cromoglycate compared to normal saline injection group. Conclusions: It is suggests that commonly used antihistamine(H2 receptor blocker) has protective effect against ischemia-reperfusion injury to skin and muscle flaps by reducing neutrophil and mast cell. The mast cell stabilizer was not effective for skin flap but, possibly, for muscle flap.

In this study we have investigated the pharmacokinetics and tissue distribution of GX-12, a multiple plasmid DNA vaccine for the treatment of HIV-1 infection. Plasmid DNA was rapidly degraded in blood with a half-life of 1.34 min and was no longer detectable at 90 min after intravenous injection in mice. After intramuscular injection, plasmid DNA concentration in the injection site rapidly declined to less than 1 ％ of the initial concentration by 90 min post-injection. However, sub-picogram levels (per mg tissue) were occasionally detected for several days after injection. The relative proportions of the individual plasm ids of GX-12 remained relatively constant at the injection site until 90 min post-injection. The concentration of plasmid DNA in tissues other than the injection site peaked at 90 min post-injection and decreased to undetectable levels at 8 h post-injection. The rapid in vivo degradation of GX-12 and absence of persistence in non-target tissues suggest that the risk of potential gene-related toxicities by GX-12 administration, such as expression in non-target tissues, insertional mutagenesis and germline transmission, is minimal.

Purpose: Glucose has been recommended as an analgesic for mild to moderately painful procedures in neonates. The goal of this study was to assess the optimal dextrose concentration for pain control in newborns. Methods: This prospective, randomized, blinded clinical trial included 116 healthy full-term newborns. The neonates were randomly assigned to the following four groups by drawing straws: groups receiving sterile water or a 10%, 20%, or 40% dextrose solution orally. Each group was treated with the assigned solution prior to hepatitis B vaccination. The Neonatal Facial Coding System (NFCS) and the Neonatal Infant Pain Scale (NIPS) scores were evaluated before, immediately after, and 2 minutes after the injection in all neonates. Premature Infant Pain Profile (PIPP) scores were evaluated during the injection. All procedures were video-recorded, and pain scores were assessed by two independent observers who were not involved in the care of the newborns studied. The pain scores were compared among the four groups. Results: The 40% dextrose solution significantly reduced the NFCS (P=0.002) and the PIPP scores (P=0.001) compared with sterile water. No hyperglycemic events were noted in the study subjects 2 hours after the injection. Conclusion: The 40% dextrose solution effectively relieved pain due to intramuscular injection in full-term newborns without causing hyperglycemic events. However, the 10% and 20% dextrose solutions did not affect neonatal pain scores.

Homocystinuria is a metabolic disorder caused by a deficiency of cystathionine ${\beta}$-synthase (CBS). Patients with homocystinuria show clinical symptoms such as mental retardation, lens dislocation, vascular disease with life-threatening thromboembolisms and skeletal deformities. Generally, the major treatments for CBS deficiency include pharmacologic doses of pyridoxine or dietary restriction of methionine. However, there is no effective treatment for this disease up till today and gene therapy can be an attractive novel approach to treatment of the disease. We investigated whether a recombinant adeno-associated virus could be used as a CBS gene transfer vector to reduce the excessive homocysteine level in the homocystinuria mouse model. Recombinant adeno-associated virus vector encoding the human CBS gene (rAAV-hCBS), driven by EF1-a promoter, was infused into CBS-deficient mice ($CBS^{-/-}$) via intramuscular (IM) and intraperitoneal (IP) injection. IP injection was more efficient than IM injection for prolongation of lives and reduction of plasma homocysteine levels. After 2 weeks of gene transfer by IP injection, serum homocysteine level was significantly decreased in treated mice compared with the age-matched controls and the life span was extended about 1.5 times. Also, increased expression of CBS gene was observed by immunohistochemical staining in livers of treated $CBS^{-/-}$ mice and microvesicular lipid droplets was decreased in cytoplasm of liver. These results demonstrate the possibility and efficacy of gene therapy by AAV gene transfer in homocystinuria mice.

The early studies demonstrated that the relative amount of FSH was important for stimulating normal ovarian activity and demonstrated the existence of a threshold level for FSH, above which follicular growth was activated. It was found that only a modest increase in circulating FSH level above the threshold (between 10 and 30%) was required to stimulate folliculogenesis. In addition, FSH is primary responsible for initiating estradiol production through the activation of the aromatase enzyme system in granulosa cells, follicular secretion and growth. LH on the other hand, plays a supportive role in ovarian steroidogenesis, stimulating the ovarian thecal cells to produce androgen, the precursor for estradiol synthesis. But there is now an increasing number of reports in the literature demonstrating an adverse effect of LH on fertility and miscarriage in infertile and fertile women. So HP-FSH is the drug of a highly purified FSH preparation which has a higher specific activity and far fewer impurities than FSH. This study was performed to evaluate the efficacy and safety of HP-FSH administered (SC; subcutaneous) versus FSH(IM; intramuscular) for ovulation induction. 20 candidates patients for ovulation induction were participated. All patients underwent pituitary desensitizing with a long gonadotropin-releasing hormone (GnRH) agonist protocol and ovulation induction was started with HP-FSH SC (10 patients; group I) or FSH IM (10 patients; group II). After ovulation, outcome of ovulation induction and local reaction of injection site were compared. There were no difference of outcome of ovulation in two groups except pregnancy rate/embryo transfer. Group I had a higher pregnancy rate/ embryo transfer than Group II (44.4% Vs 28.6%). Pain, redness, tenderness, bruising and itching when the injection received on the first 5 days of treated (50 SC and 50 IM injections) were assessed. There were no significant difference (P>0.05) in the incidence of tenderness, bruising and itching between the IM and SC injection. But IM injection (FSH) had a tendency of higher above incidence. The number of reports of pain, redness were significantly increased in IM injection group (P<0.05). These results indicate that SC administration of HP-FSH has been shown to be as effect for superovulation as traditional gonadotropins, with an improved safety profile due to the removal of extaneous proteins.

It has been demonstrated that the injection of naked DNA expressing vascular endothelial growth factor 165(VEGFl165) to the affected area can provide significant therapeutic effects on peripherol artery occlusive diseases. Success with this type of gene therapy highly depends on the quality of the vector delivering the therapeutic gene, especially in terms of the level and duration of gene expression in the localized area. We have recently developed a vector expressing VEGF165(pCK-VEGF) for the treatment of peripheral artery occulsive diseases and demonstrated high level expression of VEGF165 in mouse skeletal muscle. This study was designed to assess the acute toxicity of intramuscularly injected pCK-VEGF in BALB/c mice and Sprague-Dawely rats. There was no evidence of any changes in clinical signs, body weights, or gross pathological signs. We estimate LD50 values of pCK-VEGF higher than 50mg/kg in mice and 20 mg/kg in rats by intramuscular injection.
