Histologically, Schmorl's nodes are defined as the loss of nuclear material through the cartilage plate, growth plate, and end plate into the vertebral body. Most Schmorl's nodes are asymptomatic, although there are some reports of symptomatic Schmorl's nodes, which should be treated similarly to vertebral compression fractures, with conservative treatment as the first choice. We report the case that we reduced the pain by blocking the ramus communicans nerve in a patient with Schmorl's node.

The purpose of this study was to examine the increased bone loss caused by ovariectomy through monitoring the concentrations of the collagen and the pyridinoline crosslinks of collagen. The ovariectomized rats treated for 8 weeks, were divided at random into two or three groups of 10. Ovariectomies were carried out from the saline-treated group (Ovx), the estrogentreated group (Ovx+ES) and chondroitin sulfate-treated group (Ovx+CS). Sham operations were performed on the sham-operated group (Sham). Ovx+ES and Ovx+CS groups showed the remarkably increased collagen and pyridinoline amount in the bone and cartilage compared to Ovx group. And as the result of the measurement of SOD, Catalase and GPx which are antioxidant enzyme, SOD and Catalase activities in Ovx group were much higher than in Sham group. But they were significantly decreased in Ovx+CS group. Based on these results, it is supposed that estrogen and condroitin sulfate can enhance collagen synthesis and affect the pyridinoline formation in collagen fibrils through stimulating lysyl oxidase activity. And it is also thought that chondroitin sulfate can inhibit aging by reducing antioxidant enzyme.

Historically, the decision to perform a hemiarthroplasty (HHR) versus a total shoulder arthroplasty (TSA) is based on the status of the glenoid and the status of the soft tissues (rotator cuff). In disease processes where the glenoid articular cartilage is relatively well preserved such as avascular necrosis and complex proximal humerus fractures, most orthopaedists recommend performing a HHR while preserving the native glenoid articular surface. At the other end of the spectrum, if the glenoid has excessive bone loss or is unreconstructible, a HHR is the preferred procedure. In patients who have deficient so(t-tissues (rotator cuff) such as rotator cuff tear arthropathy and, occasionally, rheumatoid arthritis, a HHR is the procedure of choice. The indications for HHR in osteoarthritis remain somewhat controversial. There is mounting evidence that performing a HHR for osteoarthritis is inferior to TSA. Recent developments, or 'third generation techniques and materials', in shoulder arthroplasty are expected to improve the longevity of TSA, particularly the glenoid component. In addition, newer designs of reverse-ball prostheses are entering the market with promising early results in patients with deficient rotator cuff mechanisms.

갱년기의 여성에는 여러 폐경 증후들이 나타나는데, 특히 에스트로겐의 감소로 인한 혈중의 지질 조성의 변화 등으로 인한 심혈관계 질환과 골 손실의 증가로 인한 골다공증의 위험성이 높아 이에 대한 예방 및 치료에 대한 연구가 활발히 이루어지고 있다. 따라서 본 연구에서는 쉽게 섭취 할 수 있으며,부작용이 없는 해조류인 청각 추출물을 난소제거술을 통한 갱년기 유도 흰쥐에 투여하여 결합조직 중의 collagen과 pyridinoline함량, 혈 중 ALP활성 변화를 통해 갱년기 장애 질환의 개선효과를 알아보았다. 청각 추출물이 골 노화에 미치는 영향을 실험 한 결과 난소 절제에 의한 골 손실에 의해 결합조직의 collagen 함량이 감소하였으나, 청각 추출물의 투여로 인해 증가하는 경향을 보였다. 따라서 청각 추출물이 에스트로겐 감소로 인해 저하되는 collagen 합성능을 회복 시켜 유익한 효과를 가지는 것으로 추측된다. 또한 골 및 연골조직에서 collagen 성숙가교인 pyridinoline 함량을 HPLC에 의해 측정한 결과, 연골 중 pyridinoline함량은 난소절제에 의해 감소되었으나 청각 추출물 투여로 인해 난소를 절제하지 않은 SHAM군과 비슷한 수준으로 증가하여 pyridinoline 생성에 유익한 효과를 나타내었다. 이상의 결과로부터 갱년기 장애 시 유발되는 골 노화에 청각 추출물이 유효한 효과를 나타낼 것으로 기대된다.

여성의 폐경에 의한 estrogen의 감소는 골다공증을 유발시킨다고 알려져 있다. 최근 새로운 식품으로 각광받고 있는 도라지 추출물을 인위적 갱년기 장애를 유발시킨 흰쥐에 투여하여 혈 중 ALP활성 변화와 골 중의 collagen의 함량 및 collagen 가교물질 pyridinoline과 deoxypyridinoline 함량 변화를 측정하여 그 효과를 검토해 보았다. 도라지 추출물을 갱년기를 유도한 흰쥐에 투여하여 혈 중 ALP활성 변화에 미치는 영향을 검토한 결과 난소절제에 의하여 ALP활성이 증가하였으나, 도라지 추출물 투여한 군에서 ALP활성이 억제되는 것을 확인할 수 있었다. 또한 난소 절제에 의해 연골의 collagen 함량이 감소되었는데, 이는 도라지 추출물을 투여함으로써 정상적인 수치로 증가하는 경향을 나타내어 도라지 추출물이 골 대사와 관련된 골 대사 질환에 유효한 효과를 나타낼 것으로 추측된다. 또한 collagen 가교물질로써 골대사의 biomaker인 pyridinoline 및 deoxypyridinoline의 골 중의 함량은 난소절제에 의해 감소하였고, 도라지 추출물 투여에 의해 증가하여 estrogen부족으로 인한 골 손실에 도라지 추출물이 유익한 효과를 가지는 것으로 보이며, 이는 도라지 중에 함유되어 있는 phytoestrogen에 의한 것으로 추측되어 앞으로 구체적인 검토가 필요한 것으로 사료된다.

The effects of cryosurgery on tear production and histological changes of the third eyelid were studied in dogs. Clinically normal 12 mixed breeds weighing 2∼6 kg were divided into three groups and treated as follows; 45 seconds double freeze-thaw treated group, 60 seconds double freeze-thaw treated group and 90 seconds double freeze-thaw treated group. The significant decrease of the tear production after cryosurgery was shown in all groups throughout the observed periods(p<0.05). However, there was no difference among groups. The main complications after cryosurgery were chemosis and conjunctival injection. Other complications such as eyelid edema, eyelid depigmentation and keratitis were more preominent in group III compared to those of groups I and II. On histopathological examination, chronic inflammatory changes and regeneration of the third eyelid glands were noted in group I and predominated loss of the third eyelid glands and necrosis of hyaline cartilage were observed in group III However, such changes were less appeared in group II. The results of this study suggested that double freeze-thaw cryosurgery for 60 seconds on the third eyelid glands would be the most effective method for treating tear staining syndrome.

Congenital chloride diarrhea (CLD) is a rare autosomal recessive disease that is difficult to diagnose. CLD requires early treatment to correct electrolyte imbalance and alkalosis and to prevent severe dehydration. Renal injury is clearly associated with defective electrolyte balance induced by CLD, particularly during the first months or years of life. A 7-year-old boy was diagnosed with CLD following detection of a homozygous mutation (c.2063-1G>T) in SLC26A3 at 6 months of age. During treatment with electrolyte supplements, mild proteinuria was detected at 8 months of age, and is still present. Renal biopsy showed the presence of focal renal dysplasia, with metaplastic cartilage and mononuclear cell infiltration, calcification, and fibrosis in the interstitium. Up to two-thirds of the glomeruli exhibited global obsolescence, mostly aggregated in the dysplastic area. In nondysplastic areas, the glomeruli were markedly increased in size and severely hypercellular, with increased mesangial matrix, and displayed segmental sclerosis. The marked glomerular hypertrophy with focal segmental glomerulosclerosis suggested a compensatory reaction to the severe nephron loss or glomerular obsolescence associated with renal dysplasia, with superimposed by CLD aggravating the tubulointerstitial damage.

Rheumatoid arthritis is characterized by focal loss of cartilage due to an up-regulation of inflammatory pathways, which produce pro-inflammatory mediators, such as interleukin-1(IL-1), tumour necrosis factor alpha($TNF-\alpha$), prostaglantin, and nitric oxide(NO). We investigated the anti-arthritic effects of water extracts from Pellodendri cortex and Atractylodis rhizoma in vitro and in vivo. Each extract suppressed the production of inflammatory mediators(NO, $IL-1\beta$, $TNF-\alpha$, and prostaglandin $E_2$) and the expression of inducible NO synthase and cyclooxygenase-2 in lipopolysaccharide-stimulated macrophages in a dose-dependent manner. These suppressive effects were synergistically increased by their combination. The same results were also observed in the rat osteoblast sarcoma cell line ROS17/2.8 stimulated with $IL-1\beta$, $IFN-\gamma,$ and $TNF-\alpha$. Moreover, the combination of these water extracts significantly suppressed collagen-induced mouse arthritis. These results suggest that the combination of water-extractable components of Pellodendri cortex and Atractylodis rhizoma may be useful for therapeutic drugs against rheumatoid arthritis, probably by suppressing the production of inflammatory mediators.

Purpose: We defined osteoarthritis of the knee as knee pain and crepitus in over 40 years old. The usual clinical manifestation include pain, stiffness, crepitus and loss of function. Methods: We studied 40 cases of the degenerative arthritis of knee clinically. The body mass index(BMI, weight(kg)/height($m^2$) was used as a measure of obesity. Pain self assessment scale by Million Index in according to age, occupation, BMI. Results: Gender by pain self assessment scale was 6.5 in male and 6.6 in female(P<0.05). The prevalence rates obese was 40%. Occupation by pain self assessment scale was 7.0 in Sitting and 5.7 in Standing(P<0.05). Prevalence was increased with age by pain self assessment scale in aged 40-69 years. Conclusion: It has been known that the obesity is one of the predispsing factors of the primary degenerative arthritis of knee. A flexion weight bearing view of the knee obtained at $30^{\circ}$ to $40^{\circ}$ of the joint flexion may be more sensitive in assessing damages to hyaline cartilage because the knee flexion is an important component of the stance phase.
