Aging as continous biological process, affect all organic systems. Aging is believed to affect the structure and function of the enteric nervous system. Prymary aim these studies is to verify changes in number of neurons in myenteric nervous plexus of human stomach within relation to process of aging. In the course of research played is analysis number of neurons in myenteric nervous plexus of anterior wall stomach. Analysis was performed within 30 tissue samples which are classified into three age groups: (from 20 to 44 years, from 45 to 64 years and over 65 to 84 year old). Played is histological processing and stained with HE, Cresyl-violet, AgNO3 and AChE methods. The morphometric measures operated by morphometric multipurpose test system M42. Finding results are statistically processed by Student-t-test and analysis of variance. Discernible is very heavy loss of neurons of myenteric plexus within the oldest group in relation to younger groups. Applied test show are having statistically notable variance between age groups. In percentage, the loss of neurons in the oldest group in relation to others was from 13,81% to 15,44%.

Copper is an essential element, a constituent of all living cells and an integral component of many enzymes. The increase in pollution of the environment, and various metabolic diseases, imbalances biological processes and homeostatic regulated content of bioelements in the body. For the purpose of determining changes in the contents of bioelements with increased intake of copper, the paper followed by interaction before and after ingestion of copper. The results showed that copper in excess causes disruption of physiological interactions of bioelements in tissues and significantly increases the content of iron and magnesium. The nature and relationships of these interactions are important, because in terms of exposure to metals, there are changes in their mutual relations, with some of these antagonistic relationships may be utilized for further study in order to protect them from toxicity.

Rheumatoid arthritis is a chronic multisistemic disease of an unknown cause characterised by persistens inflammatory synovitis which results in destruction cartilage and bone erosions. RA is a systemic disease with various out of joint manifestations of different clinical importance, among which rheumatoid knots, rheumatoid vasculitis, pleuropulmonal and ophthalmological manifestations are the most prominent ones. The most frequent changes of the eye in patients with RA are keratoconjunctivitis sicca (KCS), episcleritis and scleritis and ulcerous keratitis. Out of 70 examined patients, 52 (74.3%) are female, and 18 (25.7%) of male sex (ratio 4:1), average age 56.47. In 18 (25.71%) RA diseased patients eye changes found are as folows: secondary Sjögren syndrom, that is keratoconjunctvitis sicca in 18.57%, only in female patients, episcleritis nodosa and scleritis in 4.29%; 2.86% in male and 1.43% female patients and ulcerous keratitis in 2.86% RA diseased patients. 

Diabetic retinopathy is the microangiopathy which procedures pre capillary arterioles, capillaries and post capillary venules. The length of disease and poor metabolic control, have the biggest impact on development and progression of DR. By the prospective study in Gracanica Health House, for the period time of six months, there were matched 50 patients with DM tip 2.Along of internal review, there were made ophthalmological review, and anthropometric and laboratory researches.

Even 1000 years BC the famous Persian physician Aviccena describet the first time gangrene diabetes mellitus as a complication. Basic pathohistological substrate vascular complication is atherosclerotic plaqueand therefore is an adequate treatment opf patients with vascular disease is conditioned by timely and precise diagnosis.The introduction of ultrasound technology in clinical practice enabled Edler and Hertz when the shou moves infarction 1954th,a then and Yoshida (1956.) and Sotomura (1959.), Frenklin (1961.) who are using ultrasound display of blood flow in the courts of man. The aim of our study was to deterimne the frequency of occurrences of atherosclerotic plaque in the carotid arteries and ultrasound examination of differences in the variability of certain plaques between patients with diabetes mellitus type 2 and healthy subjects. The examination was attended by a total of 82 people divided into two group. In first group they are 51 persons suffering from diabetes mellitus type 2 in to second control, the number of healthy respondents was 31. Among our respondents, a significantly higher incidence and plaque vulnerability was ina group of patients with diabetes mellitus type 2. 

In diabetics fungal skin infections are reported to be related to greatly disturbed metabolism. In order to get better insight into the association between diabetes mellitus and fungal skin infections, we started our study with the aim to assess the effect of metabolic regulation on the incidence of fungal skin infections is diabetics. The obtained results of our study show that in patient with metabolically poorly regulated primary disease i.e. diabetes the incidence of the fungal skin infections is highest (36.0%), its incidence is lower in patients with metabolically satisfactorily regulated diabetes (29.5%) and lowest in those with well regulated diabetes (18.8%), witch is statistically significant difference (p=0.045).

In the region of the thorax there are ten till twelve ganglia (ganglia thoracica); wich are white; triangle and irregular shape; rarely fusiform (spindle-shaped) or round. In the upper part of the thorax; ganglia are located in front of of the neck of ribs (collum costae); and in the middle part they are in front of head of ribs (caput costae). In the lower parts; they are near the vertebral bodies; therefore both of the trunks are slightly convergent. In this part; there are no branches which connected both sides of the sympathetic trunk. Lipofucin is yellow-brown; autofluorescent pigment; accumulated during aging in the lysosome of postmitotic cells; such as neurons.

Type 2 diabetes represents a progressive disease, primarily characterised by impairment of glycoregulation, despite the application of various therapy modalities. The main problem with type 2 diabetes, is progressive impairment of betacell functioning, and impairment of insulin resistance. There is an ongoing pursuit after adequate therapy modalities aiming at preservation of beta-cell function followed by loss of weight and assurance of good glycoregulation. For mentioned reasons, research has been done recently on the functioning of enteropancreatic axis in type 2 diabetes. It has been noted that oral intake of food or glucose leads to higher increase in secretion of insulin in comparison to the intake of the same quantity of glucose intravenously, resulting in assumption that hormone signals from endocrine cells of intestine released by the intake of food represent potent stimulators of insulin secretion. Such role is played by GLP-1 and GIP, GIT peptide hormons which stimulate secretion of insulin and release themselves into blood when stomach himus penetrates into duodenum, that is before glucose from himus is absorbed into internal body media. Persons with type 2 diabetes have got low level of secreted GLP-1 after meal. Chronic administration of GLP-1 agonists leads to reducing glycemia and HbA1c. The potential of GLP-1 agonists to decelerate progressive decay of beta-cells at diabetics is alluring, but insufficiently documented. DPP-IV inhibitors represent complementary approach for provoking incretin effects, by oral intake of pills.

Renal osteodystrophy is significant medical, economic and social problem. Over 90% of patients receiving chronic dialysis are facing some type of renal osteodystrophy. The objective of the study is to determine correlation between clinical and radiological findings in patients with renal osteodystrophy. Clinical study was performed in 60 adult patients, different sex and ages, receiving chronic dialysis, with developed renal osteodystrophy. All patients were having following symptoms: bone pain, muscle and joint pain. Muscle spasm were registered in 68.3% of patients, while proximal myopathy symptoms were registered in 86.6%.Dominant radiological findings were: subperiosteal resorption in 53.3% of patients, diffuse osteoporosis in 48.3%, rugger jersey in 33.3% and soft tissue calcification in 18.3%. We have registered statistically significant correlation of clinical and radiological findings. With this study we have confirmed that different types of renal osteodystrophy can be determined by comparing radiological, clinical and biochemical findings, especially in cases when bone biopsy cannot be performed.
