The purpose of this study is to report a clinical case of a patient with CIPN (Chemotherapy Induced Peripheral Neuropathy) successfully treated with Korean medicine interventions including acupuncture, herbal medicine and moxibustion. The patient is a female with CIPN who was diagnosed with ascending colon cancer and suffering from paresthesia of extremities after chemotherapy of platinum compounds. The patient was treated mainly with electroacupuncture (Ex-LE 10), indirect moxibustion and herbal medicine (Ucha-Shinki-hwan granule). The clinical outcomes were measured by NCI CTCAE grade, EORTC QLQ-C30 (CIPN20) scale and patient's assessment of symptoms. In this case, the NCI CTCAE grade was improved from II to I. The scores of global health status and functional scale in QLQ-C30 were increased and symptom scale was decreased. Especially, this case shows a noticeable decrease in sensory scale in QLQ-CIPN20. In patient's general assessment, the scale was changed from 10 to 5. Korean medical interventions including acupuncture, herbal medicine and moxibustion could potentially be an effective treatment for CIPN if further researches are conducted.
We investigated the effects of polyacetylenes of ginseng on farnesyl protein transferase (FPTase) and carboxyl methyl transferase (CMTase) activities related to post-translational modification of Ras protein. We also investigated the effect of petroleum ether extract (PEE) of ginseng on progression of cell cycle. FPTase activity was respectively inhibited 16.2% by 10mM panaxynol and 21.3% by 10mM panaxydol, whereas CMTase activity was not inhibited by panaxynol or panaxydol. Treatment of PEE significantly reduced the numbers and size of human colon cancer cell (HT-29) and human liver cancer cell(HepG2) cultured, respectively. To investigate the mechanism of growth inhibition by PEE of ginseng, we analyzed the cell cycle progressions of PT-29 and HepG2 cells, respectively. We found that PEE significantly inhibited progression of cell cycle from G1 to S phase. These results suggest that anticancer effects of PEE were derived from the arrest of G1 phase in cell cycle progression.

Increased antimutagenic and in vitro anticancer effects were observed by the fermentation process during Kochujang manufacturing. In order to confirm the increased functionality, wheat grain, first fermented wheat grains (FFWG), second fermented wheat grains (SFWG), final fermented wheat grains (FiFWG), red pepper powder (RPP), and commercial Kochujang (CK) were prepared. Kochujang manufactured with final fermented wheat grains and red pepper powder were further fermented for 15 days and 30 days. The antimutagenic effects were determined by counting the number of revertants in Salmonella Typhimurium TA100 against N-methyl-N'-nitro-nitrosoguanidine (MNNG, 1.0mg/mL). The final fermented wheat grains (52% inhibition) showed higher antimutagenic effects than the wheat grain (34%), and the commercial Kochujang showed the highest antimutagenic effects (55%). We tested the inhibitory effect on the growth of HT-29 human colon carcinoma cells and AGS human gastric adenocarcinoma cells by using MTT (3-(4,5-dimethyl-thiazol)-2,5-diphenyltetrazolium bromide) assay. The results showed that increased fermentation process continually increased the growth inhibitory effect on both cancer cells. The further fermentation for 15 days of the Kochujang product also increased inhibitory growth of the AGS cancer cells. In conclusion, the methanol extract from fermented wheat grains and commercial Kochujang showed sequentially increased antimutagenic and in vitro anticancer activity, and thus the final commercial Kochujang revealed the highest effect.
This study was performed to determine the antimutagenic and anticancer effects of ethanol extract of buckwheat sprout using Ames test and SRB assay, respectively. An ethyl acetate fraction (200 ${\mu}/plate$) from the ethanol extract of buckwheat sprout showed inhibition rate of 80.6% against the mutagenesis induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) in Salmonella typhimurium TA100 strain. Also the ethyl acetate fraction (200 ${\mu}/plate$) showed higher antimutagenic activity than other fractions against the mutagenesis induced by 4-nitroquinoline-1-oxide (4NQO) in Salmonella typhimurium TA98 and TA100. In addition, the ethyl acetate fraction (200 ${\mu}/plate$) showed high antimutagenic effect of 80.9% and 85.9% against the mutation of TA98 and TA100 strains induced by 3-amino-1,4-dimethyl-5H-pyrido-(4,3-b)indol (Trp-P-1), respectively. The cytotoxic effects of each solvent fraction from the ethanol extract of buckwheat sprout against human cancer cell lines including lung carcinoma (A549), gastric carcinoma (AGS), breast adenocarcinoma (MCF-7), hepatocellular carcinoma (Hep3B), and colon adenocarcinoma (Colo 205) were investigated. The ethyl acetate fraction of buckwheat sprout ethanol extract at the concentration of 1.0 mg/ml showed strong cytotoxic activities of 70.3, 94.8, 79.6, 82.3, and 73.2% against A549, AGS, MCF-7, Hep3B and Colo 205 cancer cell lines, respectively.
It has been known that retinoids are intrinsically of critical importance for control of premalignant epithelial cell differentiation. In the absence of retinoids, normal cellular differentiation and growth does not occur in epithelia such as those of trachea and bronchi. Furthermore, it was also reported that retinoid deficiency enhanced susceptibility to chemical carcinogenesis in the respiratory system, in the bladder, and in the colon of the experimental animal. In 1974, Bollag examined the effects of synthetic retinoids in prevention of development of cancer and demonstrated synthetic retinoids to have more favorable therapeutic index than retinoic acid for causing regression of skin papilloma in mice. Therefore, it was assumed that this anticarcinogenic effect of vitamin A derivatives could be due to modification of the metabolism of the carcinogenic polycyclic hydrocarbon, which must first be activated to exert their effect. Hill and Shih reported that vitamin A compounds and analogs had inhibitory effect on drug metabolizing enzyme from liver and lung tissue of mouse and hamster. Lucy suggested that the chemoprevention effect of vitamin A derivatives is due to reaction with molecular oxygen, and it is possible that inhibition of hydroxybenzpyrene formation is a result of this property. On the other hand, butylated hydroxytoluene which is a potent antioxidant strongly inhibited the formation of mammary tumor induced by dimethylbenranthracene. Also, it was observed that this antioxidant inhibited cancer induction in rats by N-2-fluo-renylacetamide. The purpose of this experiment was to investigate the effect of vitamin A derivatives such as retinoic acid and retinoid on drug-metabolizing enzyme and to determine whether riboflavin tetrabutylate or vitamin E could prevent of modify any changes induced by vitamin A delivatives in the rats. The results obtained were as followings. 1) Body weight was significantly reduced by retinoic acid, but not by retinoid. 2) Retinoic acid markedly increased liver weight while retincid showed no effect on liver weight. Treatment of riboflavin tetrabutylate did not affect retinoic acid-induced change in both body weight and liver weight. 3) Both retinoic acid and retinoid remarkably decreased the activity of aminopyrine demethylase. Pretreatment of riboflavin tetrabutylate, however, prevented inhibitory effect of retinoic acid on the enzyme activity. 4) No significant effect of vitamin E on aminopyrine demethylase was observed in both groups treated with retinoic acid and retinoid.
This study was conducted to confirm the availability of lactic acid bacteria as probiotics haying inhibitory effects to cancer cell line. Five lactic acid bacteria showing anti-cancer activity were compared by acid tolerance, bile tolerance, antibiotics resistance, milk fermentation, stability, and cell adherence activity to colon epithelial cell. The results obtained are as follows : In acid tolerance, all strains did not have a resistance below pH 3.0 and 3.5 except Lactobacillus plantarum KCTC3099. In antibiotics resistance, Lactococcus lactis and L. plantarum KCTC3099 were resistant to cotrimoxazol (128 mg/1), and Bifidobacterium adolescentis Maeil-K8 and B. infantis Maeil-K9 were resistant to doxycylin and gentamycin (4 mg/1). In case of cell adherence ability to Caco-2 cell, B. infantis Maeil-K9 was found to be superior to others as 3.1%, while the others were less than 0.5%. When the strains were cultured to milk base, viable counts of the strains tested increased more 1 log cycle than inoculation, but acid production was very low except L. plantarum KCTC3099. Also, L. plantarum KCTC3099, B. adolescentis Maeil-K8, and B. infantis Maeil-K9 were stable in fermented milk base during storage. In conclusion, L. plantarum KCTC3099 and B. infantis Maeil-K9 were confirmed to be superior for the availability as probiotics.

Germ-line mutations at DNA repair loci confer susceptibility to colon cancer in hereditary non-polypopsis colorectal cancer. Somatic loss of DNA mismatch repair gene has been reported in a large variety of other tumor types. Replication errors(RERs) judged by microsatellite instability(MSI) and its associated mutations have been recognized as an important mechanism in various tumor types. To investigate associations between MSI and oral squamous cell carcinoma, the frequency of MSI using 12 microsatellite markers were analyzed for the series of oral tumors. Of 17 tumors, 8 cases(47%) did not show instability at any of the 12 loci; 5(29%) showed instability at $2{\sim}3$ loci; and 4(24%) showed instability above 4 loci. The 4 cases showing widespread MSI did not differ from those without evidence of instability in terms of age at diagnosis, degree of differentiation, metastasis to lymph node, tumor location or the presence of mutations in the p53 tumor suppressor gene. DCC and D17S 796 were the most frequently detected in MSI analysis. There were no correlation between smoking and MSI frequency, instead, smoking was suggested to increase the mutation rate of p53 and development of oral carcinomas.

There were many controversies in the cause and progress of tumorigenesis. Recently, studies on the mutation of genes related to the tumor have extensively been performed due to development of molecular biology. Structural and morphological changes of chromosomes, which are related to the abnormal activation of oncogenes or inactivation of tumor suppression genes, transform the normal cells into the tumor cells. p53 and Rb are well known tumor suppressor genes, while oncogenes include c-myc, bcl-2 and ras, etc. When exposed to cell damaging agents, p53 inhibits cell growth by inducing transcription of p21. Especially p73, which is homo-logy of p53, frequently deleted in melanoma, neuroblastoma, colon cancer, and breast cancer, when over produced, p73 activates the transcription of p21, bax-1 and inhibits cell growth by inducing apoptosis. For study on mRNA expression of p21 and p73, normal oral keratinocytes, and cell lines of primary and metastatic oral squamous cell carcinoma were cultured and then electrophoresis and RT-PCR(reverse transcription-polymerase chain reaction) were performed. 1. The mRNA of p21 and p73 in normal oral keratinocyte expressed lower than that of primary squamous cell carcinoma. 2. The mRNA of p21 in metastatic oral squamous carcinoma cell lines was expressed as various patterns compared with that of normal oral keratinocyte. 3. In the metastatic oral squamous cell lines, the mRNA of HN8 expressed higher than that of HN12 or HN19. 4. The mRNA of p73 in primary oral squamous cell lines expressed 4-5 times higher than that of normal keratinocyte. 5. In metastatic oral squamous cell lines, there was no significant expression of p73 mRNA compared with that of normal oral keratinocyte. From the results obtained in this study, mRNA expression of p73 in primary oral squamous cell lines was remarkable, while mRNA expression of p21 and p73 in metastatic oral squamous cell lines were statistically insignificant.

This study was conducted on the antioxidant activity and in vitro anticancer effects of rough rice (Oryza sativa L.) by germination periods. Rough rice was germinated at $37^{\circ}C$ for 8 days and then extracted with 70% ethanol. It was then analyzed for total polyphenol content, reducing power, antioxidant activities, and in vitro anticancer effects. Total polyphenol content increased from 3.12 mg/g for raw rough rice to 4.05 mg/g at 4 days of germination. Also reducing power increased from 0.96 to 1.25 (p<0.05). DPPH radical scavenging activity increased from 29.25% at 0 day to 34.82% at 2 days. ABTS radical scavenging activity increased from 3.05 mg AA eq/100 g at 0 day to 3.84 mg AA eq/100 g at 4 days, and then decreased afterward. The anticancer effect of ethanol extract at 4 days on stomach cancer cell line (AGS) and colon cancer cell line (HCT-116) showed higher values compared with raw rough rice extract. These results suggest that the best germination periods for increasing biological activities may be 3~4 days.
Aim: To present an epidemiological and histological perspective of diseases of the gastrointestinal tract (including liver and biliary tract) at the Section of Histopathology, Department of Pathology, AKUH, Karachi, Pakistan. Materials and Methods: All consecutive endoscopic biopsies and resections between October 1 and December 31, 2012 were included. Results: A total of 2,323 cases were included. Carcinoma was overwhelmingly the commonest diagnosis on esophageal biopsies (69.1%); chronic helicobacter gastritis (45.6%) followed by adenocarcinoma (23.5%) were the commonest diagnoses on gastric biopsies; adenocarcinoma (27.3%) followed by ulcerative colitis (13.1%) were the commonest diagnoses on colonic biopsies; acute appendicitis (59.1%) was the commonest diagnosis on appendicectomy specimens; chronic viral hepatitis (44.8%) followed by hepatocellular carcinoma (23.4%) were the commonest diagnoses on liver biopsies; chronic cholecystitis was the commonest diagnosis (over 89%) on cholecystectomy specimens. Conclusions: Squamous cell carcinoma comprised 88.8% of esophageal cancers. About 67% were in the lower third and 56.5% were moderately differentiated; mean ages 49.8 years for females and 55.8 years for males; 66% cases were from South West Pakistan. Over 67% patients with gastric adenocarcinoma were males; mean ages 59 and 44 years in males and females respectively, about 74% gastric carcinomas were poorly differentiated; and 62.2% were located in the antropyloric region. About 63% patients with colorectal adenocarcinoma were males; mean ages 46.1 and 50.5 years for males and females respectively; tumor grade was moderately differentiated in 54%; over 80% were located in the left colon. In 21.2% appendicectomies, no acute inflammation was found. Acute appendicitis was most common in young people. Hepatitis C (66.3%) was more common than hepatitis B (33.7%); about 78% cases of hepatocellular carcinoma occurred in males; females comprised 76.7% patients with chronic cholecystitis; and 77.8% patients with gall bladder carcinoma. All resection specimens showed advanced cancers. Most cancers occurred after the age of 50 years.
