Benign prostatic hyperplasia (BPH) is frequently observed in intact middle-aged or older male dogs with symptoms ranging from asymptomatic to various symptoms such as urination, dyschezia, dysuria, tenesmus, and intermittent serosanguinous or clear serous exudate. A 4-year-old, intact male Welsh corgi with symptoms of intermittent hematuria and serosanguinous exudate at the urethral opening was diagnosed with BPH and intraprostatic hematocyst through ultrasonographic examination and cytology test. The dog was internationally adopted for reproductive purposes and needed to undergo BPH treatment while maintaining fertility. Thus, 2.5 mg finasteride was administered orally once a day for treatment option and therapeutic effects were observed, including loss of clinical symptoms and reduced prostate and intraparenchymal cyst size.

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a vascular inflammatory disease characterized by painless mass in the dermis, subcutaneous tissue, or both in the head and neck region. However, occurrence in the oral mucosa is extremely rare. In this study, we report a case of ALHE that occurred on the upper lip and discuss the histopathological features and management.

Intravascular papillary endothelial hyperplasia (IPEH) is an unusual reactive benign lesion of vascular origin caused by endothelial cell proliferation, which rarely occurs in oral cavity. IPEH appears in various forms because it has non-specific clinical presentation, so it can be misdiagnosed as a malignant lesion.Therefore, it is important to make a differential diagnosis by understanding the characteristics of this lesion.We report a case of IPEH in a 22-year-old Korean female patient, discussing about differential diagnosis and treatment. This report presents review of literature and describes a case of IPEH.

만성담낭염에 흔히 동반되는 담낭의 선근종증은 육안적 형태에 따라 분절형, 국소형, 미만형의 세가지로 분류할 수 있다. 선근종증에서 드물게 담낭암의 전구성병변이나 담낭암이 발생하기도 하는데, 대부분 분절형 선근종증에서 기원하는 것으로 알려져 있다. 담낭암의 전구성병변 중 하나인 담낭내 유두모양종양은 담낭의 점막 상피에서 기원하여 내강 내로 자라면서 용종이나 유두종을 형성하는 것이 일반적이다. 이번 증례에서 담낭 점막의 용종이나 유두종을 형성하지 않고 근육층에 국한되어 있으면서 국소형 선근종증에서 유래한 담낭내유두모양종양 1예를 보고하고자 한다.

“Cartilaginous choristoma” refers to as a tumorlike cartilaginous mass composed of normal tissues in an abnormal location. Oral cartilaginous choristomas are extremely rare. Although its rarity, most intraoral choristomas occur in the tongue. Adenomatoid hyperplasia of the minor salivary glands may be seen on the minor salivary gland bearing areas, especially seen on the palate. This report describes a case of firm mass on the left lateral tongue that was resulted cartilaginous choristoma associated with adenomatoid hyperplasia, which occurred in a 23-year-old male patient. And It hasn’t recurred during 17 months after complete excision.

The lower urinary tract symptoms (LUTS) show in benign prostatic hyperplasia (BPH). The three major micturition centers in brain are pontine micturition center (PMC), ventrolateral periaqueductal gray (vlPAG), and medial preopticnucleus (MPA) regions. Previous study showed that c-Fos expression change was associated with LUTS. In present study, the effect of P. ginseng on c-Fos expression in PMC, vlPAG, and MPA regions in rat brain was tested. P. ginseng is the four year-old Korean ginseng. It was collected at the department of medicinal crop research (Eumsunggun, Chungbuk, Korea) in September 2010. The four groups (n = 6) are control group, BPH-induced group, BPHinduced and P. ginseng-treated group, and BPH-induced and finasteride-treated group. BPH in rats was induced by testosterone. After 4 weeks, all animals were sacrificed to evaluate c-Fos expression in PMC, vlPAG, and MPA regions in rat brain. The c-Fos expression was evaluated in the regions of rat brain by immunohistochemistry (IHC). Present results showed that c-Fos expressions in PMC, vl-PAG, and MPA regions in brain of rats in the BPH-induced group were higher compared to c-fos expression of the control group. The increased c-Fos expression in three regions (PMC, vlPAG, and MPA) were decreased by treatment with P. ginseng (200 mg/kg). These results suggest that P. ginseng has an inhibitory effect on the symptoms of BPH and is associated with regulation of c-Fos expression in the brain in a testosterone induced BPH rat model.

The follicular lymphoid hyperplasia is a very rare nonneoplastic lymphoproliferative disease in the oral mucosa. Clinically, it usually presents as asymptomatic, non-ulcerated, normal-colored, soft, sessile, unilateral and slow growing mass in the posterior hard palate. Therefore, soft-tissue mass of the hard palate can be a difficult diagnostic challenge for the clinician. Herein, we report a case of follicular lymphoid hyperplasia located in the left posterior hard palate. A 40-year-old male presented a soft, non-ulcerated, painless mass of 1.5 X 1.0cm in size. Radiographically, it was no bony involvement. Histology revealed germinal center surrounding mantle zone of small lymphocytes. Immunohistochemistry showed CD3,CD20 were postive but Bcl-2 and cyclin D1 were negative. The patient underwent surgical excision and 3-year follow-up has not shown any evidence of recurrence.

Intravascular papillary endothelial hyperplasia (IPEH) is a rare benign vascular lesion that rarely occurs in the oral cavity. Its clinical features are similar to neoplasms, which are easily identified in the oral cavity, and it can be misdiagnosed as an angiosarcoma. Therefore, it is important to recognize the characteristics of the lesion in order to both diagnose and treat it properly. We report a case of IPEH in a young Korean female patient, as well as discuss its differential diagnosis and treatment using a review of the related literature.

Considering the dearth of information regarding the medicinal properties of Luffa cylindrica, we assessed the antioxidative, antimutagenic and hyperplasia inhibitory activity of cancer cells from Luffa cylindrica extracts by employing biological and biochemical assays. Ethanol extracts of Luffa cylindrica inhibited MDA-BSA (malondialdehyde-bovine serum albumin) conjugation reaction (66.38±2.65), DPPH (1, 1-diphenyl-2-picryl-hydrazyl) radical production (60.13±0.42) and lipid peroxidation (56.04±3.24). In this study, Luffa cylindrica is believed to exert possible antioxidative effects. The direct and indirect antimutagenic effects of the ethanol extracts of Luffa cylindrica were examined by the Ames test using Salmonella typimurium TA98 and TA100. The inhibitory effects on indirect and direct mutagenicity shows an weak tendency, particularly in direct mutagenicity mediated by 2-nitrofluorene in Salmonella typimurium TA98 (5.82±5.74) and in indirect mutagenicity mediated by 2-anthramine in Salmonella typimurium TA100 (5.76±2.15). The ethanol extracts of Luffa cylindrica on cancer cell hyperplasia inhibitory activity via MTT (3-(4, 5-dimethylthiazol-2-yl)-2, 5 diphenyltetrazolium bromide) assay exerted cytotoxic effects on Hela cells (55.83±3.83) and MCF-7 cells (33.03±2.09), which were used in this study. Based on these results, it believed that the ethanol extracts of Luffa cylindrica have antioxidative capacities as well as hyperplasia inhibitory activity of cancer cells. Furthemore, Luffa cylindrica is a candidate for the prevention and dietetic treatment of chronic diseases and for the development of functional food.

A 41-year-old male patient complained of a whitish growing mass on the central area of palate. The exophytic keratinizing mass was recently grown and showed rough surface localized at palatal mucosa. He has heavily smoked for more than 25 years. The lesion was clearly demarcated as an out-growing verrucous whitish epithelial lesion with erosive mucosa in the periphery and also continuous with the extensive hyperkeratosis in whole hard palatal mucosa. In the histological examination there appeared a plaque type verrucous hyperplasia in the absence of papillomatous growth. In the series of immunostains including PCNA, p53, β-catenin, APC, E-cadherin, BCL-2, MMP-1 and MMP-3 showed no features of infiltrative growth and malignant transformation. Therefore, the present case was diagnosed oral verrucous hyperplasia(OVH) different from squamous cell papilloma, verrucous leukoplakia, verrucous carcinoma, and oral squamous cell carcinoma.

곰취(Ligularia fischeri)의 이용성을 높이데 필요한 기초자료를 확보하고자 메탄올을 용매로 하여 추출 온도 및 시간에 따른 생리활성 효과를 조사하였다. 곰취 메탄올추출물 1,000mg·L-1에 함유된 총 페놀함량, 총플라보노이드 함량은 각각 75.8-297.7mg·L-1 and 45.6-173.6mg·L-1이었다. 추출온도와 시간은 총 페놀함량, 총 플라보노이드 함량, 전자공여 능 의 경우 95℃에서 6시간 동안 추출했을 때 가장 좋았다. 그러나 아질산염 소거능은 75℃에서 12시간 추출한 것에서 97.4%로 가장 높게 나타났다. 곰취 메탄을 추출물 200mg·L-1 및 400mg·L-1 농도는 각각 폐암과 위암세포 증식을 90% 이상 억제시켰다. 따라서 곰취는 높은 생리활성 기능을 나타내는 채소로 나타났으며, 곰취를 가공품으로 이용하기 위해 메탄올로 추출할 때는 95℃에서 6시간 정도 하는 것이 좋을 것으로 생각되었다.

We evaluated the efficacy and safety of plasmakinetic transurethral enucleation and resection (TUERP) for benign prostatic hyperplasia (BPH) more than 80g. From January 2011 to December 2013, 37 patients with BPH larger than 80 g who underwent plasmakinetic TUERP were retrospectively assessed. The postoperative outcomes such as operative time, resected adenoma weight, resection rate, catheterization time, postoperative hospital stay and complications were reviewed. Patients were followed up at 1, 3, 6 months postoperatively. The mean prostate volume was 108.7 ± 21.7 g (range, 80 to 200 g), The mean resection chip weight was 53.5 ± 15.7 g (range, 29 to 101 g), The mean resection ratio was 82.0 ± 12.9%. Catheterization time and hospital stay was 2.4 ± 1.6 days and 3.4 ± 1.6 days respectively. Perioperative loss of hemoglobin and serum sodium was 1.5 ± 0.8 g/dL and 2.3 ±2.0 mmol/L respectively. International Prostate Symptom Score (IPSS), quality of life (QOL) score, maximum flow rate (Qmax), post void residual urine volume (PVR) were significantly improved at all followup intervals compared with baseline. No major complication including TUR syndrome was developed. Plasmakinetic TUERP is considered a safe, effective and technically feasible procedure for the large volume BPH more than 80 g at shortterm followup.
