We examined the hepatoprotective effects of colored potato flakes on acetaminophen (AAP)-induced liver damage in rats. F344/DuCrj (8 week-old) rats were fed a cholesterol-free diet with 54.9486 g of ${\alpha}$-corn starch/100g diet and were orally treated with 25% colored flakes of Kitamurasaki (KM: light purple), Northern Ruby (NR: red), and Shadow Queen (SQ: medium purple) potatoes co-administered with AAP (0.5 g/100 g diet) for 4 weeks. The hepatic thiobarbituric acid-reactive substances (TBARS) values in the KM, NR, and SQ groups were significantly lower (p<0.05) than those in the control groups with and without AAP. Furthermore, the hepatic catalase, Mn-superoxide dismutase (SOD), and Cu/Zn-SOD mRNA levels in the KM, NR, and SQ groups were higher than those in the control groups with and without AAP. The present findings suggest that colored potato flakes are useful as a prophylactic agent against oxidative liver damage.
Bujeonghangamtang(扶正抗癌湯) has been used for cure of tumor as a traditional medicine without any experimental evidence to support the rational basis for its clinical use. This study was carried out to evaluate the possible therapeutic or antitumoral effects of Bujeonghangamtang extract against tumor, and to carry out some mechanisms responsible for its effect. Some kinds of tumor were induced by the typical application of 3-methylcholanthrene. (MCA) or by the implantation(s.c) of malignant tumor cells such as leukemia cells(3LL cells) or sarcoma cells(Sl80 cells). Treatment of the Bujeonghangamtang water-extract (dailly 1mg/mouse, i. p.) was continued for 7 days prior to tumor induction and after that the treatment was lasted for 20 days. Against squamous cell carcinoma induced by MCA, Bujeonghangamtang decreased not only the frequency of tumor production but also the number and the weight of tumors per tumor bearing mice (TBM). Bujeonghangamtang also significantly suppressed the development of 3LL cell and S180 cell-implanted tumors in occurrence-frequency and their size, and some developed tumors were regressed by the continuous treatment of Bujeonghangamtang extract into TBM. In vitro, treatment of Bujeonghangamtang extract had no effect on the growth of some kinds of cell line such as FsaII, A431 strain but significantly inhibited the proliferation of 3LL, S180 cells and augmented the DNA synthesis of mitogen-activated lymphocytes. Bujeonghangamtang also stimulated the migrative ability of leukocyte, the MIF and IL-2 production of T lymphocytes, but not IL 6 production of B cells. Bujeonghangamtang-administration to mice enhanced NK cells activities. These results demonstrated that Bujeonghangamtang extract exhibited a significant prophylactic benefits against tumors and its antitumor activity was manifested depending on the type of tumor cells. And these results also suggested that effect of Bujeonghangamtang might be chiefly due to nonspecific enhancement of NK cell activities and cell-mediated immune responses.
Purpose: This study investigated the long-term clinical outcomes of patients with $p22^{phox}$-deficient chronic granulomatous disease (CGD) on Jeju Island and retrospectively evaluated the effects of interferon-gamma (IFN-${\gamma}$) prophylaxis. Methods: The medical records of 15 patients with CGD were retrospectively reviewed. The efficacy of IFN-${\gamma}$ prophylaxis was evaluated by comparing the frequency of severe infections before and after starting continuous prophylaxis with IFN-${\gamma}$. Results: At the time of the analysis, 14 patients were alive, with a median age of 14.3 years. The diagnosis of CGD was made at a median age of 2.4 years, and the median age at onset of severe infection was 0.3 years. Thirteen of the 15 patients had their first severe infection within the first year of life. The overall incidence of severe infection was 1.36 infections per patient-year; pneumonia, suppurative lymphadenitis, and skin and subcutaneous abscesses were the most common infections. Aspergillus species were the most frequently isolated microorganisms, present in 15.8% of isolates. IFN-${\gamma}$ did not significantly change the rate of severe infection. The survival rate for patients after 2 years of age was 93%; there was a prolonged survival plateau beyond the age of 2. Conclusion: Compared with cases of X-linked CGD reported in other studies, patients with CGD on Jeju Island did not show obviously different clinical manifestations, but they had a significantly higher survival rate. Further studies with a substantially longer period of observation, and with more patients under intensive surveillance are necessary to elucidate the prophylactic efficiency of IFN-${\gamma}$.

Our study focused on the antioxidant activities of Mosidae leaf ethanol extract (MLE) and included measurements of reducing power, total phenolic compounds, DPPH radical scavenging activity, and hydroxyl radical scavenging activity. In order to determine whether or not MLE evidences any chemopreventive activities, experimental lung metastasis was induced via the i.v. inoculation of colon26-M3.l carcinoma cells into BALB/c mice. Additionally, we attempted to characterize any possible cytotoxic effects in murine normal splenocytes and tumor cells (B16-BL6 and colon26-M3.1). The total phenolic content and reducing capacity were measured at 39 mg/100 mL and 1.24, respectively, whereas the DPPH and hydroxyl radical scavenging activities of MLE were measured to be 88.89% and 22.10%, respectively. Prophylactic i.v. treatment with MLE resulted in a dose-dependent and significant inhibition of lung metastasis. Specifically, a MLE dose of 200 ug per mouse resulted in an 88.90% inhibition of lung metastasis. For the cytotoxicity assay, MLE doses up to 100 ug/mL were not shown to affect the growth of normal murine splenocytes. Additionally, the survival of normal cells was not affected at MLE doses below 500 ug/mL. However, MLE doses up to 500 ug/mL reduced the percentage of tumor cell growth for B16BL6 (67% alive) and colon26-M3.1 (62% alive) cells.

Botulinum toxin (BoNT) injections have been used not only in the field of cosmetic surgery such as forehead and eye wrinkle treatment but also in the treatment of chronic migraine, dystonia, spasticity, temporomandibular disorders (TMD). BoNT injections are the only approved therapies to date for prophylactic treatment of chronic migraine patients. Unlike the previously known paralysis of motor neurons, the mechanism of action for migraine is to block the release of non-cholinergic neurotransmitters such as substance P, CGRP, and glutamate, which are associated with peripheral sensitization and neurogenic inflammation in the sensory nerve, it is hypothesized that the signal is blocked. This review focuses on the analgesic effects of BoNT and suggests the direction for the development of injection methods for chronic migraine patients.

Background: The first line of anti-tuberculosis (TB) drugs are the most effective standard of drugs for TB. However, the use of these drugs is associated with hepatotoxicity. Silymarin has protective effects against hepatotoxicity of anti-TB drugs in animal models. This study aims to investigate the protective effect of silymarin on hepatotoxicity caused by anti-TB drugs. Methods: This is a prospective, randomized, double-blind and placebo-controlled study. Patients were eligible if they were 20 years of age or order and started the first-line anti-tuberculosis drugs. Eligible patients were randomized for receiving silymarin or a placebo for the first 4 weeks. The primary outcome was the proportion of patients who showed elevated serum liver enzymes more than 3 times the upper normal limit (UNL) or total bilirubin (TBil) > $2{\times}UNL$ within the first 8 weeks of anti-TB treatment. Results: We enrolled a total of 121 patients who silymarin or a placebo to start their anti-TB treatment, for the first 8 weeks. The proportions of elevated serum liver enzymes more than 3 times of UNL at week 2, week 4, and week 8 did not show any significant difference between the silymarin and placebo groups, at 0% versus 3.6% (p>0.999); 4.4% versus 3.6% (p>0.999); and 8.7% versus 10.8% (p=0.630), respectively. However, patients with TBil >$2{\times}UNL$ at week 8 were significantly low in the silymarin group (0% versus 8.7%, p=0.043). Conclusion: Our findings did not show silymarin had any significant preventive effect on the hepatotoxicity of anti-TB drugs.
Background: Human papillomavirus (HPV) infection is the main cause of cervical cancer. Limited epidemiologic data of HPV prevalence are available for women attending hospitals in southern China. This study aimed to evaluate the profiles of HPV infection and cytology status in gynecological outpatients in Chaozhou City. Methods: A total of 2833 eligible women were enrolled. The HPV GenoArray test was used for HPV detection and genotyping. Nearly one half of the HPV positive women received liquid-based cytology test. Logistic regression analysis was performed to assess the predictable effects of age and genotype for categories of abnormal cytology. Results: The prevalence of overall, high-risk, and low-risk HPV infection were 24.5%, 19.5% and 8.4%, respectively. A U-shaped age-specific prevalence curve was observed in overall HPV and high-risk HPV, but not in low-risk HPV, which declined with age increasing. The 6 most common high-risk HPV type in descending order, were types 52, 16, 58, 18, 68, and 33. Age and HPV genotype were both important determinants of abnormal cytology incidence, the older women (>45 years) and those infected with HPV type 16 and/or 18 having the highest risk for abnormal cytology. Conclusion: Our findings support the hypothesis that second-generation HPV prophylactic vaccines including HPV-52 and -58 may offer higher protection for women residing in Chaozhou and neighboring cities in Guangdong.
The aqua-acupuncture blended with liquid medicine and acupuncture is known to be effective in treating various medical disorders. This study used gallbladders of bear (WoongDam, WD, Ursus arctos Linne) and pig(JeoDam, JD, Sus scrofa domestica Brisson) plus the stones from the ox gallbladder(WooHwang, WH, Bos taurus var, domesticus Gmelin) to produce the liquid medicine. For the acupuncture, acupoint of ST -36 which is located one finger breadth from the anterior crest of the tibia was selected. There were a couple of purposes in this experiment. First, the relationship between aqua-acupuncture and gastric activity was scrutinized. Secondly, the possibility of pig gallbladder as an alternative organ to bear gallbladder for making liquid medicine was evaluated. Thirdly, different injection concentration ratio of liquid medicine was tried to figure out the optimal dosage for the aqua-acupuncture. The data of the present results indicated that the mixtures of WD + WH and JD + WH have a similar hypotonic effect on the stomach. These findings illustrated that aqua-acupuncture or hydroacupuncture showed inhibitory effect on the stomach in addition to its well-known prophylactic value. Also the possible alternative medical organ of pig gallbladder was checked out since two mixtures illustrated very similar trends in suppressing the gastric activity. The injection concentration ratio was not very different between two mixtures in terms of gastric motility except a couple of ratio. In conclusion, the aqua-acupuncture is a promising way to control the gastric activity for better medical purposes and the gallbladder of pig was assessed as a prospective one for making a liquid medicine.

The antidotal, anticonvulsant and neuroprotective effects of physostigmine and procyclidine. the combinational prophylactics for organophosphate poisoning, were evaluated in rats. In comparison with a low protective effect (1.6 fold) of atropine (15 mg/kg) and 2-pralidoxime (30 mg/kg), the traditional antidotes regimen, a marked protection ratio of 7.3 fold was achieved by combinational pretreatment with physostigmine (0.05 mg/kg) and procyclidine (10 mg/kg), which was superior to that (3.5 fold) with pyri-dostigmine (0.1 mg/kg) and atropine (15 mg/kg). Rats exposed to a high dose (10 mg/kg. 2 X $LD_{50}$) of diisopropylfluorophosphate showed severe epileptiform seizures on electroencephalography, resulting in necrotic and apoptotic brain injuries in discrete brain regions under histopathological and TUNEL immuno-histochemical examinations in 24 hr. Such seizures and excitotoxic brain injuries were fully prevented by pretreatment with physostigmine (0.05 mg/kg) and procyclidine (10 mg/kg). in contrast to a negligible effect of pyridostigmine (0.1 mg/kg) and atropine (15 mg/kg). Taken together, it is proposed that the prophylactics composed of physostigmine and procyclidine could be a promising regimen for the prevention of lethality, seizures and brain injuries induced by organophosphate poisoning.
A flock of AA breed chickens were reared in peterstme brood-vait chamber and were provided with high energy pelleted feed. At 14 d of age, a total of 350 birds were randomly divided into 3 groups as follows: 100 birds were exposed to normal ambient temperature of 20$^{\circ}C$ for control group; 150 birds were exposed to lower ambient temperature of 11$^{\circ}C$ to induce ascites (treatment I); and another group of 100 birds were exposed to lower ambient temperature of 11$^{\circ}C$ and fed diet containing 1% L-arginine for ascitic prophylactic treatment (treatment II). Samples were collected from blood and abdominal fluid of chicken at 3, 4, 5, 6 and 7 wk of age subsequently, to analysis the contents of plasma endothelin (ET-1), angiotensin II (Ang II), cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP). The results indicated that the contents of cAMP, cGMP, and Ang II in reatment I and ascitic broilers were higher than the corresponding control group (p<0.01, p<0.05), ET-1 of preascitic broilers were control group (p<0.05), while there was an insignificant difference with later ascitic broilers. The contents of cAMP and cGMP in treatment II were higher than the treatment I and control groups (p<0.01, p<0.05), whereas, the contents of Ang II were gradually decreased compared to the control group (p<0.05), the contents of ET-1 were insignificantly different. On further analysis, the increased plasma Ang II at low ambient temperature condition in broilers made endothelium cell secretion of increased ET-1, cAMP, cGMP and decreased NO. Therefore, low temperature accelerated ascites syndrome in broilers. Supplemently L-arginine can decrease ET-1, and increase cAMP and cGMP. It is concluded that cAMP mediated in broilers pulmonary hypertension syndrome.
