Comedones appear as blackheads and whiteheads and implicate cutaneous zones with dense sebaceous follicles, particularly the face, upper chest or dorsal torso. Acne vulgaris is frequently enunciated with comedones. Hyper-proliferation and aberrant desquamation of ductal keratinocytes is enunciated which impedes sebum exudation within a pilo-sebaceous duct, thus engendering comedones. Also, a prototypicpilo-sebaceous duct unit metamorphoses into a comedone when progenitor component of the sebaceous glands differentiate into epithelial-like cells.“Micro-comedone theory” cogitates acne configuration as “comedogenesis” which is contingent to androgen secretion, hyper-proliferating keratinocytes with accumulation of keratin and sebum within the pilo-sebaceous unit. Hyperkeratinisation is also due to secretion of pro-inflammatory cytokines interleukin -1 alpha (IL-1α) produced as a result of cutaneous colonization of Propionibacterium acnes.

Propionibacterium acnes plays an important role in the pathophysiology of acne vulgaris, the most common chronic inflammatory skin disease of the pilosebaceous unit. This study was conducted to investigate whether the entomopathogenic fungus Polycephalomyces phaothaiensis components have antibacterial and anti-inflammatory effects against P. acnes that may serve for acne treatment. A chemical study by spectroscopic analysis resulted in the identification of seven known compounds. The anti-P. acnes potency of extracts and test compounds was determined by both agar diffusion and broth dilution methods. The ethyl acetate extract from culture broth along with cordytropolone (1) and stipitalide (2) exhibited strong anti- P. acnes activity while (+)-piliformic acid (3) showed weak inhibitory activity. The anti-inflammatory effect of ethyl acetate extract and 1–3 was then examined by the quantification of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α on heat-killed P. acnes induced cytokine production by THP-1 cells. The result demonstrated that the extract and its constituents (1–3) showed a potent significant effect by inhibiting the P. acnes-induced pro-inflammatory cytokines production in THP-1. Our results suggest for the first time that P. phaothaiensis and its constituents (1 and 2) hold therapeutic value for further studies as a new alternative treatment for acne.

This study investigated splenic status changes in weaned Sprague-Dawley rats induced by lipopolysaccharide. There were forty 26-day-old rats selected randomly and equally divided into two groups. The treatment group received daily single doses of lipopolysaccharide, and the control group was treated with normal saline. We conducted haematoxylin-eosin staining, immunohistochemical staining and semi-quantitative optical density analysis for both groups on the 29th, 32nd, 35th and 38th days after treatment. The results indicated that splenic marginal zone in the lipopolysaccharide group was thinner or disappeared compared to that of the saline group. However, the periarterial lymphoid sheath and the diameters of splenic lymphoid follicles appeared thicker and wider than those in the saline group (P less than 0.05). The expression of interleukin-1 beta, interleukin-6 and tumour necrosis factor alpha was mainly localized within the periarterial lymphoid sheath and splenic lymphoid follicles in the lipopolysaccharide treated rats. The integrated optical density and the average optical density in the lipopolysaccharide group were greater than those in the normal saline treated group (P less than 0.05). In conclusion, splenic immune function is probably strengthened by altering microstructures and releasing pro-inflammatory cytokines following lipopolysaccharide treatment.

The article presents the description of the changes in the concentrations of pro‐inflammatory cytokines and soluble forms of selectins and immunoglobulin superfamily adhesion molecules in patients with chronic generalized slight periodontitis. Serum concentrations of interleukin‐1‐β, tumor necrosis factor‐ α, soluble forms of P‐ and E‐selectins, intercellular adhesion molecule (ICAM‐1), vascular adhesion molecules (VCAM‐1) and platelet‐endothelial adhesion molecules (PECAM‐1) in healthy subjects and patients with slight periodontitis before and after treatment were assessed. It was found that the serum concentration of sICAM‐1, sVCAM‐1, sP‐, sE‐ selektins and pro‐inflammatory cytokines are increased in patients with chronic generalized periodontitis. The increase of serum concentration of soluble forms of selectins is expressed more significantly than sICAM‐1 and sVCAM‐1. There are no statistically significant changes of serum sPECAM‐1 in the examined group of patients in comparison with control. Complex therapy, including etiological and pathogenetic treatment, is completely normalized the concentration of pro‐inflammatory cytokines, and soluble forms of studied endothelial adhesion molecules in patients with chronic generalized slight periodontitis. All the studied parameters in patients with chronic generalized slight periodontitis after treatment are in the range of the control group variability.

Annotation. Obesity is a problem of the third millennium. It is known that obesity is a major factor in the development of various diseases, including acute pancreatitis. Obesity itself is a pro-inflammatory condition with elevated levels of the following pro-inflammatory cytokines: tumor necrosis factor (TNF-a), interleukin (IL) IL-10, IL-6, IL-1b. Acute pancreatitis is also a disease based on the pathogenesis of the cytokine reaction and autolysis. Thus, against the background of the already formed inflammatory response, the inflammatory response intensifies and increases, and the level of pro-inflammatory cytokines reaches critical values. The purpose is to study the effect of ulinastatin on the severe acute pancreatitis in obese patients. To refute or confirm the hypothesis among patients with severe acute pancreatitis and obesity (BMI was 37.48±2.19 kg / m2), two groups were randomized. In the first group (experimental) of 18 patients, a step-up approach was performed. In the second group (control), the total number of which was 18 patients, a standard treatment algorithm was performed. The experimental group suggested the use of early resuscitation with Ringer’s lactate and ulinastatin in the first 5 days of the disease. The drug was administered at a dose of 200,000 IU by intravenous infusion for 1 hour 3 times a day for 5 days. In the control group, resuscitation was performed with 0.9% sodium chloride solution without the use of ulinastatin. Hypothesis was tested by monitoring procalciton and C-reactive protein, interleukin-1 and interleukin-6 over a period of 24 hours, 48 hours, 10 days, 15 days, 30 days, 45 and 60 days. The choice of procalcitonin and CRP was made by calculating the relative risk, as the level of CRP> 200mg / l indicated the preservation of severe disease (RR=2.07; 95% CI=1.65-2.59; p=0.01), and an increase in procalcitonin> 1.8 ng / mg was a predictor of infection (RR=2.27; 95% CI=1.083-4.769; p=0.02). The use of ulinastatin during the first 5 days in the experimental group reduced the level of interleukin-1 from 23.64±4.13 to 8.71±2.49 pg / ml (p=0.001; α=0.05), interleukin- 6 – from 29.72±4.27 to 12.43±2.36 pg / ml (p=0.001; α=0.05). The use of resuscitation with Ringer's lactate solution in combination with ulinastatin for 5 days helped to reduce the level of procalciton in 1.8 times (2.89±0.88 compared with 1.8±0.23 ng / mg; p=0.001; α=0.05). The level of CRP during the period of ulinastatin decreased by 41.68 (267.28±114.11 compared with 225.6±84.9 mg / l; p=0.01; α=0.05). In-hospital mortality was significantly lower in the ulinastatin group (16% vs. 69.6%; p=0.0003; α=0.05). Significantly lower proportion of patients (24% compared to 73.9%; p=0.0005; α=0.05) with multiple organ failure among the study group. Organ dysfunction was acquired on day 5 among patients taking ulinastatin. The length of hospital stay was 49.7±4.2 bed-days, while in the comparison group – 56.67±5.84 bed-days (p=0.01; α=0.05). Thus, the use of Ringer-lactate early resuscitation in combination with ulinastatin has improved the treatment of severe acute pancreatitis in obese patients.

Though Ayurveda is India's ancient traditional medicine written Thousands of years back, its concepts and principles are useful in today's era also. My small research work can be one example of it. Mukhdushika also was known as Youvanpeetika is a common health problem found in Adolescence which disturbs physical psychological and social health. Mukhdushika known as acne vulgaris is the classical stigma of adolescence and inflammation of sebaceous glands which produces physiological and psychological scarring. Dashang lepa is commonly used for shotha in clinical practice, but when it was applied as lepa on the face, its effectiveness was observed in mukhadushika. So after considering effective experience in mukhadushika I decided to go for its systematic study through this small research work, to study the effect of dashang lepa in mukhadushika.

Non-specific illness includes a wide variety of symptoms: behavioural (e.g., reduced food and water intake), cognitive (e.g., memory and concentration problems) and physiological (e.g., fever). This paper reviews evidence suggesting that such symptoms can be explained more parsimoniously as a single symptom cluster than as a set of separate illnesses such as Gulf War Syndrome (GWS) and chronic fatigue syndrome (CFS). This superordinate syndrome could have its biological basis in the activity of pro-inflammatory cytokines (in particular interleukin-1: IL-1), that give rise to what has become known as the ‘sickness response’. It is further argued that the persistence of non-specific illness in chronic conditions like GWS may be (in part) attributable to a bio-associative mechanism (Ferguson and Cassaday, 1999). In the case of GWS, physiological challenges could have produced a non-specific sickness response that became associated with smells (e.g., petrol), coincidentally experienced in the Persian Gulf. On returning to the home environment, these same smells would act as associative triggers for the maintenance of (conditioned) sickness responses. Such associative mechanisms could be mediated through the hypothalamus and limbic system via vagal nerve innervation and would provide an explanation for the persistence of a set of symptoms (e.g., fever) that should normally be short lived and self-limiting. We also present evidence that the pattern of symptoms produced by the pro-inflammatory cytokines reflects a shift in immune system functioning towards a (T-helper-1) Th1 profile. This position contrasts with other immunological accounts of GWS that suggest that the immune system demonstrates a shift to a Th2 (allergy) profile. Evidence pertaining to these two contrasting positions is reviewed.
