  • Background: Male and female breast cancers were investigated for variation in the clinicopathologic characteristics and expression of steroid hormone receptors in the northeast of Iran. Materials and Methods: Tumor specimens of 17 males and 338 females with breast cancer were collected at the hospitals of Mashhad University of Medical Sciences. Immunohistochemical expression of hormone receptors and clinicopathologic features of breast cancer were compared between two groups. Results: The mean age in men was 15 years higher than women (p=0.000). Males and females were mainly in stage II and III respectively (p=0.007). Although more than 60% of male and female patients were grade II, the respective figures for grade I and III were 25% and 12.5% in men but 7.1% and 27.2% in women respectively (p=0.025). ER was significantly more positive in men against women; 82.3% versus 53.4% (p=0.016). The related measures for PR was 58.8% and 50.3%, respectively (p=0.424). Males also showed significantly more ER expression than postmenopausal females; 82.3% versus 48.9% (p=0.010). Conclusions: Breast cancer in males and females contrasted in age at diagnosis, histological type, stage, grade and ER expression which emphasize they are separate diseases with different behaviors.

  • Background: Malignant melanoma is a cancer that demonstrates rapid progression and atypical clinically features with a poor prognosis. Aim: This study was performed to determine the clinical characteristics and treatment outcomes of patients with malignant melanoma in Turkey. Methods: The medical records of 98 patients between 2007-2012 at our centers were retrieved from the patient registry. Overall survival (OS) was calculated using the Kaplan-Meier method. Results: In our study, with the median follow-up of all patients with cutaneous MM of 46.3 months, the median OS rate of all cases was 43.6 months and 5-year OS was 48.6%. However, five-year OS rates of patients with localized disease (stage I-II) and node involvement (stage III) were 60.3% and 39.6%, respectively. The median OS of stage IV patients was 8.7 months and 1-year OS rate was 26.2%. We showed that advanced stage, male gender, and advanced age in all patients with MM were significant prognostic factors of OS. Conclusions: Compared with the results of current studies from Western countries, we found similar findings concerning demographical features, histological variables and survival analyses for our patients with cutaneous MM in Turkey.

  • The Ovarian developmental phases of the reproductive cycle of Rapana venosa can be classified into five successive stages by histological study: early active stage (September to February), late active stage (December to April), ripe stage (March to July), partially spawned stage (May to August), and recovery stage (June to September). To understand the characteristics of nutrient storage and utilization in the digestive gland cells with ovarian developmental phases, we examined the digestive gland - which is the major nutrient supply organ associated with ovarian development of the female purple shell - by biochemical methods. Total protein contents in the digestive gland tissues increased in March (late active stage) and reached the maximum in May (ripe and partially spawned stages), and then their levels sharply decreased in July (partially spawned and recovery stages). Total lipid contents in the digestive gland tissues reached the maximum in January (early active stage). Thereafter, their levels rapidly decreased from May (ripe and partially spawned stages) and reached a minimum in July (partially spawned and recovery stages). The total DNA contents did not significantly change regardless of the different developmental stages of the ovary. However, it was also found from biochemical analysis that changes in total RNA content follow the same seasonal cycling to protein. These results indicate that the digestive gland is an important energy storage and supply organ in purple shells, and that the nutrient contents of the digestive gland change in response to gonadal energy needs.

LCH는 비교적 좋은 예후를 기대할 수는 있으나, 좀더 장기간의 추적조사 및 전신적 검토, 관련 타과와의 협조가 필요하다.

  • A keratoameloblastoma is a histologically variant of the ameloblastoma group, which varies in size and contains keratin material in the fibrous connective tissue among cystic lesions. A keratoameloblastoma is a rare disease with only 13 cases reported in the literature since Pindborg's first report in 1970. A 41-year-old man visited, complaining of pus discharged from the right maxilla. He had been diagnosed with an odontogenic keratocyst and was treated with cyst enucleation in the past. The clinical and radiology examination found evidence of recurrence and finally diagnosed him with keratoameloblastoma after enucleation and biopsy. This report discusses the clinical, radiological and histological characteristics of keratoameloblastoma and its treatment. In addition, we report another case of keratoameloblastoma that had transformed from an odontogenic keratocyst.

  • Objectives This study was designed to review the effect of herbal medicine on animal model with rheumatoid arthritis. Methods We reviewed studies published both in Korea and overseas, all published after 2008. We investigated 8 databases, 6 Korean databases and 2 of abroad. Searching was conducted through flowchart and 24 studies met our guideline. Datas were extrated and organized as animal model characteristics, experimental period, study design, herbal medicine used as intervention and rheumatoid arthritis indicator. Results 336 articles were primarily selected. After screening, 24 articles were left in the end. All 24 studies showed that the herbal medicine used in the animal experiment was effective on treating rheumatoid arthris, proven by macroscopic, histological, hematological and osteological indicators. Conclusions The result showed that herbal medicine is effective in treating rheumatoid arthritis through various pathways. However, study design and intervention were all different from each other and we could not specify the certain compound, material or substance of efficacy. Further study should be conducted to figure out the effectiveness of herbal medicine on rheumatoid arthritis.

  • Hepatoblastoma is a rare pediatric malignancy which frequently presents at an advanced un resectable stage. With the neoadjuvant chemotherapy, improved resectability and survival have been reported. Twenty children with biopsy proven hepatoblastoma were treated during the period between January 1987 and June 1995. Median age at diagnosis was 13 months(2 months to 7 year and 10 months), and 13 were male. Histologic profile was 13 epithelial(5 fetal, 4 mixed, 1 embryonal, 3 undetermined), and 5 mixed mesenchymal and epithelial and 2 of undetermined type. Chemotherapy effectively reduced the tumor volume($p$=0.008), and was able to convert 7 out of 9 initially unresectable cases(78%) to resectable ones. Twelve radical and 2 palliative operations were done with or without adjuvant chemotherapy. The Median follow up period was 33 months and the median survival was 26 months. The group with curative resection had a 61.1% 5 year survival rate, but none of palliative resection group survived more than 13 months($p$=0.0001). In univariate analysis for prognostic factors revealed, large tumor size at diagnosis and abscence of thrombocytopenia were associated with poor survival, but these differences were not statistically significant. Histological pure fetal type did not mean a better prognosis. Even with a recent neoadjuvant chemotherapy, the strategy should be focused on the radical resection as early as possible.

  • This study tested whether repeated measurement of median frequency (MDF)-related variables could express the muscle power changes during a 12-week DeLome strengthening program, by using consecutive overlapping FFT (Fast Fourier transformation) and integrated EMG (IEMG) from surface EMG data for isometric and isotonic exercise. To evaluate the effect of training, the following were recorded every 3 weeks for the elbow flexors and knee extensors of 5 healthy male volunteers: MVC, lRM, limb circumference, and surface EMG during isometric MVC or isotonic contraction at 10RM load. From the EMG data, IEMG and variables from a regression analysis between MDF and time were obtained. MVC, lRM, IEMG, and initial MDF increased linearly over the training period. The fatigue index and slope of the regression line increased temporarily until the 6th week and decreased thereafter. From these results, there appeared to be enhanced neural recruitment of fast twitch fibers in the first 6 weeks and continued enhancement in the recruitment and hypertrophy of fast twitch fibers, which led to increased fatigue resistance, over the last 6 weeks. Accordingly, the MDF and IEMG analysis technique could demonstrate the effect of the program detected significant changes in both isometric and isotonic contractions. EMG analysis methods can be used to estimate the electrophysiological and histological changes in skeletal muscles during a strengthening program.

  • In general, the root color of Codonopsis lanceolata is white, but red or blue-colored root is found at a low frequency in nature. Red or blue-colored roots have scarcity value, thus farmers wish to produce colored roots. The factors for determining the color of roots are unclear whether the color is controlled by genetically or simply by environmentally such as soil environment. Using in vitro culture system which is advantageous for setting of the same culture condition, we analyzed the physiological and morphological characteristics and genetic differences among red-, blue- and white lines of C. lanceolata. In the red colored roots, stems of in vitro cultured plantlet were colored in dark red pigment. Histological analysis revealed that the red pigment was accumulated in the outer cortex layer of the stem and determined as anthocyanin. Chlorophyll contents in red root lines were higher than those in white- and blue root lines. Plantlets from red roots were smaller in both shoot length and total leaf area than those from white- and blue roots. Genetic differences among the three different colored C. lanceolata were determined by RAPD (Randomly Amplified Polymorphic DNA) analysis. Each line of colored roots had clear DNA polymorphism. These results indicate that the occurrence of red- and blue colored roots in nature was determined by genetic factors rather than soil enviromental conditions.
