  • Background: The object of this study was to examine whether a new protocol including step-sectioning and immunohistochemistry (IHC) staining of axillary sentinel nodes (SN) would lead to detection of more metastases in patients with breast cancer. Materials and Methods: Sixty-nine tumor free sentinel lymph nodes were examined. Step frozen sectioning was performed on formalin fixed SN and stained both by hematoxylin and eosin (H and E) and cytokeratin markers using IHC. Any tumoral cell in IHC stained slides were considered as a positive result. Metastases up to 0.2 mm were considered as isolated tumor cells and 0.2 up to 2 mm as micrometastasis. Results: Mean age of the patients was $48.7{\pm}12.2$ years. Step sectioning of the SN revealed 11 involved by metastasis which was statistically significant (p<0.001). Furthermore, 15 (21.7%) of the patients revealed positive results in IHC staining for pan-CK marker and this was also statistically significant (p=0.001). Ten patients had tumoral involvement in lymph nodes harvested from axillary dissection and 4 out of 15 lymph nodes with positive result for CK marker were isolated tumor cells. However, 4 of 10 patients with tumor positive lymph nodes in axillary dissection were negative for CK marker and in contrast 6 of the pan-CK positive SN were in patients with tumor-free axillary lymph nodes. Conclusions: Both IHC and step sectioning improve the detection rate of metastases. Considering the similar power of these two methods, we recommend using either IHC staining or step sectioning for better evaluation of harvested SNs.

  • The pearl is a highly valuable gem that has historically represented wealth and power. Pearl necklaces have developed intro various types and represent an essential status item for modern women. This study first examines the symbolic and various meanings of pearls. Second, this study examines wearing types and pearl necklace patterns based on historical figures and modern fashion icons famous for personal displays of pearls. This study examines and analyzes various specialty publications about jewels, history of costumes, fashion magazines, academic research data, and internet search results. The conclusion of this study is as follows. Pearls have various symbolic meanings that are unlike other gems. Pearls represent purity, innocence, marital fidelity, an intimate relationship with the moon, frozen tears of God, solitude, triumph over adversity, wisdom, and sensual attraction. The societies and people traditionally famous for pearls were the Roman Empire, Queen Cleopatra of Egypt, Queen Theodora of the Byzantine Empire, Queen Elizabeth I, Queen Marie Antoinette, Empress of Eugenie Napoleon III, and Queen Alexandra. They showed a special affection for pearl necklaces and various wearing patterns unique to the time. Their pearl necklaces became a historic and symbolic legacy. Reestablished through the costume jewelry of cultivated pearls designed by Coco Chanel in the $20^{th}$ century, the pearl necklace has showed a variety of fashion trends in addition to a traditional symbolism of wealth and power. Josephine Baker, Louise Brooks, Marilyn Monroe, Elizabeth Taylor, Jacqueline Kennedy, Queen Elizabeth II, Princess Diana, Michelle Obama and Sarah Jessica Parker have worn notable pearl necklaces and established an individual style that utilizes the adornment of fashionable and stylish pearl necklaces. They have worn pearl necklaces while applying various fashion trend motifs to symbolic pearl features of that have changed the perception of the pearl and themselves.

  • This study was performed to examine the possibility of water extracts for several medicinal plants, such as Amomum tsao-ko, Alpinia oxyphylla, and Citrus unshiu, as an active packaging ingredient for prevention of lipid oxidation. Chicken breast meats were packed with medicinal plant extracts incorporated carrageenan based films and their physico-chemical and microbial properties during storage at $5^{\circ}C$ were investigated. In chicken meat samples packed with A. tsao-ko (TF) or A. oxyphylla (OF) extract incorporated carrageenan based films, pH value, thiobarbituric acid reactive substances (TBARS), and the population of total microbes were significantly lower than those of the negative control (film of no extract was incorporated, CF) after 5 d of storage (p<0.05). Especially, TBARS value of TF ($0.12{\pm}0.01$ mg malonaldehyde/kg meat) was significantly lower than chicken meat samples packed with positive control (ascorbic acid incorporated film, AF, $0.16{\pm}0.01$ mg malonaldehyde/kg meat) at 3 d of storage, and it means TF has enough antioxidative activity to prevent the lipid oxidation of chicken meat. However, there was no consistent effect on VBN values of chicken meats packed with medicinal plant extracts incorporated films during storage. Based on the obtained results, it is considered that A. tsao-ko extract has potential for being used as a natural antioxidant ingredient in active packaging areas.

  • A survey conducted on 1,103 patients or caretakers visited Korean medical clinics and hospitals between August 25, 2011 to September 30, 2011 by the Ministry of Health and Welfares and Korea Institute for Health and Social Affairs was analyzed and obtained following results: 1. For sociodemographic distribution, female(813) outnumbered male(290) patients with majority of patients ranging from 30s to 60s. Married patients(793) outnumbered unwed(150) patients and 65.0% with higher than high school education. Statistical significance was seen in gender, age, marital status, and education level but no significant difference for status of employment, income level, and types of insurance between the clinics and hospitals. (P<0.05). 45.1% had less than \2,000,000 in monthly salary and most of coverage was provided by either regional or work insurance. 2. 67.9% of the patients rated health conditions to be better than average and 32.1% listed as poor. People in good health showed tendency to visit Korean medical facilities. Musculo-skeletal conditions such as arthritis, ankle sprain, lumbago, muscular injury, and frozen shoulder were common conditions, followed by gastric disorders, common cold and herbal tonics. No significant difference was observed between the clinics and hospitals for above conditions, but significance was seen in atopic dermatitis, stroke, and sequela from traffic accidents (P<0.05). 3. Ten most common conditions addressed at Korean medical facilities were lumbago, arthritis, muscular injury, back sprain, gastric disorders, ankle sprain, common cold, herbal tonics, frozen shoulder and stroke. Major treatment modalities rendered were herbal medicine, herbal supplements, acupuncture and moxibustion, cupping, tuina, and Korean midical physical therapy. No significant difference existed between the clinics and hospitals. 4. All modalities showed at least 85% effectiveness. No statistical significant difference between the clinics and hospitals except for herbal decoction. (P=0.0452) 5. 88.3% of responses showed treatment satisfaction with significant difference between the clinics and hospitals (P=0.002). The occurrence of side effects was at 2%, mostly corning from treating digestive, skin, kidney disorders and neurological issues. No significant difference was observed between the clinics and hospitals. From the above results, the typical population visiting Korean medical facilities can be summarized as being middle aged female with relatively higher education and moderately low income. The health condition is generally good and the purpose of visit is to receive traditional treatments of acupuncture, herbal medicine, and physical therapy. Treatment efficacy and satisfaction were high with no significant differences between the clinics and hospitals.

  • Objectives The purpose of this review is to investigate studies of Scolopendrid pharmacopuncture and the evidence of it's effects in order to suggest a better research method in the future. Methods We retrieved numbers of clinical studies about Scolopendrid pharmacopuncture from 7 Korean web databases, using key words such as 'Scolopendrid', 'Scolopendrid AND Pharmacopuncture'. This study had been conducted from 1st May 2013 to 31th July 2013. Controlled studies and case studies were only used for this study. Clinical studies that we picked from the databases were classified according to the diseases that those studies are about, and from these clinical studies, we are to research what has to be improved generally in clinical researches. Results 18 case studies, 4 controlled studies had been under research. Scolopendrid pharmacopuncture has a therapeutic effect mainly in musculoskeletal and neurological diseases such as herniated intervertebral disc, carpal tunnel syndrome, swollen leg, feeling of cold on legs, wrist ganglion, lateral epicondylitis, radial nerve palsy, cervical myelopathy, cauda equina syndrome, postauricular pain; as an early symptom of Bell's palsy, pain of popliteal part, gout, plantar fasciitis, cellulitis, frozen shoulder, pain of hip adductors. However objectivity and reliability of the Scolopendrid pharmacopuncture studies still remains controversial. Conclusions It has been suggested that there are positive effects of Scolopendrid pharmacopuncture therapy in treating specific diseases (especially neuromusculoskeletal diseases). However, this narrative review can't conclude and prove that the Scolopendrid pharmacopuncture has positive effectiveness on these diseases unlike systematic review. So, in order to put Scolopendrid pharmacopuncture therapy to use for many kinds of diseases in more reasonable ways, it is essential to build well-designed clinical research tools. In the future, abundant case studies, more follow-up trials and randomized controlled trials based on the korean medicine should be done to use Scolopendrid pharmacopuncture for a clinical purpose.

  • The competency of garlic and pennywort to improve broiler chicken growth and influence intestinal microbial communities and fatty acid composition of breast meat were studied. Two hundred forty, "day-old" chicks were randomly allocated to 4 treatment groups consisting of 6 replications of 10 chicks in each pen. The groups were assigned to receive treatment diets as follows: i) basal diet (control), ii) basal diet plus 0.5% garlic powder (GP), iii) basal diet plus 0.5% pennywort powder (PW) and iv) 0.002% virginiamycin (VM). Birds were killed at day 42 and intestinal samples were collected to assess for Lactobacillus and Escherichia coli. The pectoralis profundus from chicken breast samples was obtained from 10 birds from each treatment group on day 42 and frozen at $-20^{\circ}C$ for further analyses. Fatty acid profile of breast muscles was determined using gas liquid chromatography. Feed intake and weight gain of broilers fed with GP, PW, and VM were significantly higher (p<0.05) compared to control. Feeding chicks GP, PW, and VM significantly reduced Escherichia coli count (p<0.05) while Lactobacillus spp count were significantly higher (p<0.05) in the gut when compared to control group on day 42. Supplemented diet containing pennywort increased the C18:3n-3 fatty acid composition of chickens' breast muscle. Garlic and pennywort may be useful in modulating broiler guts as they control the enteropathogens that help to utilize feed efficiently. This subsequently enhances the growth performances of broiler chickens.

  • Cryopreservation of epididymal sperm is an effective technique to preserve genetic materials of domestic cats and wild felids when they unexpectedly die. However, this technique inevitably causes detrimental changes of cryopreserved-thawed spermatozoa, for example, by physical damage and excessive oxidative stress. L-carnitine is an antioxidant that has been used to improve sperm motility in humans and domestic animals. This study aimed to investigate the effects of L-carnitine on cat epididymal sperm quality following cryopreservation and thawing. After routine castration, cauda epididymides were collected from 60 cat testes. The epididymal spermatozoa from 3 cauda epididymides were pooled as 1 replicate. Spermatozoa samples (16 replicates) were examined for spermatozoa quality and then randomly divided into 4 groups: 0 mM L-carnitine (control), 12.5 mM, 25 mM and 50 mM L-carnitine. The sperm aliquots were then equilibrated and conventionally frozen. After thawing, sperm motility, plasma membrane integrity, DNA integrity and acrosome integrity were evaluated. The 25 mM L-carnitine significantly improved sperm motility compared with a control group (p<0.05), although this was not significantly different among other concentrations. In conclusion, supplementation of 25 mM L-carnitine in freezing extender improves cauda epididymal spermatozoa motility. The effects of L-carnitine on the levels of oxidative stress during freezing and thawing remains to be examined.

  • Angiomyoma is a rare, benign smooth muscle cell tumor. These tumors may be found anywhere in the body. They frequently occur in the lower extremities except venous type. Angiomyoma in the head and neck area is very rare, and only a few cases have been reported. A 63 year-old male patient visited to outpatient clinic due to size-growing nodule-like lesion in the Lt. alar area. Excisional biopsy was done for diagnosis. The lesion was totally excised with 2 mm safety margin. Frozen biopsy of the lesion was requested, and all resection margins were proved negative. To cover the raw surface, full thickness skin grafting was performed. The graft was harvested from Rt. posterior auricular area. Tie over dressing was applyed on Lt. alar area. The graft was well taken and healed without any complication in both short term and long term follow up periods of 2 weeks, 1 month, 2 months, and 6 months. Donor site completed healed without any complications. The leiomyoma is benign tumor originated from smooth muscle, and it can be classified into solid leiomyoma, angiomyoma, and epithelioid leiomyoma. Especially, the angiomyoma consists of smooth muscle cell and blood vessel, and it is originated from the tunica media of blood vessel. Angiomyoma alone frequently occurs in the lower extremities as solitary painless subcutaneous tumor. Venous type of angiomyoma in the oral cavity was reported in other references, but on the facial surface it may be the first case reported as paper. So this report can be very meaningful.

  • Objective: In the present study, we aimed to retrospectively evaluate the cumulative live birth rate (LBR) after up to three consecutive embryo transfer (ET) cycles, either fresh or frozen, in women with expected poor ovarian response (ePOR). Methods: We selected 115 women who entered the first in vitro fertilization (IVF) cycle between August 2013 and July 2016. The women were divided into an ePOR group (37 women) and a non-ePOR group (78 women). All women in the ePOR group were ≥ 40 years old or had serum anti-Müllerian hormone levels of less than 1.1 ng/mL at the time of the first IVF cycle. Live birth outcomes were monitored until December 2017. The cumulative LBR (with both conservative and optimistic estimates) was calculated according to the serial number of ET cycles. Results: After up to three ET cycles, the overall cumulative LBR was significantly lower in the ePOR group than in the non-ePOR group (conservative estimate, 10.8% vs. 44.9%, respectively; optimistic estimate, 14.7% vs. 56.1%, respectively; log-rank test, p= 0.003). Conclusion: Women with ePOR exhibited a lower cumulative LBR than women in the non-ePOR group, and this information should be provided to ePOR women during counseling before starting IVF.
