柱状鼻疾病 (PSD) 和性炎 (HS) 尽管起源不同,但具有相似的免疫和上皮反应. 组织学分析显示PSD的铁和头发轴较高,每个病情都有不同的人口结构模式.
科学领域:
- 皮肤病学 皮肤病学
- 病理学 病理学 病理学
- 免疫学 免疫学 免疫学
背景情况:
- 柱状鼻疾病 (PSD) 是一种与毛囊阻塞相关的慢性炎症状况.
- 补腺炎 (HS) 是一种慢性炎症性皮肤疾病,病因不明.
- 两种PSD和HS都具有重叠的临床特征,需要进一步调查它们的潜在病理.
研究的目的:
- 为了研究Pilonidal鼻疾病 (PSD) 和hidradenitis suppurativa (HS) 之间的组织学和免疫组织化学差异.
- 为了比较PSD和HS病变中的蛋白质表达,铁含量,头发轴存在和巨细胞数量.
- 分析不同人口群体的疾病患病率.
主要方法:
- 分析了70名患者的组织和19名正常皮肤对照者,使用甲固定式嵌入的组织.
- 对细胞克拉丁5/6,KLK7,费拉格林,恩沃普拉金和EPHA2蛋白表达的免疫组合化学分析.
- 铁含量,损伤内毛轴,多核巨细胞数量和人口统计数据的比较.
主要成果:

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

01:21Accessory Structures of the Skin: Sebaceous Glands
2.4K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
