1. The activities of lysozyme, acid and alkaline phosphatases, beta-glucuronidase, amylase, lipase, glutamate-oxalacetate transaminase, and glutamate-pyruvate transaminase in the whole hemolymph and 4000 g pellets and supernatants of Mya arenaria were determined. 2. All of these enzymes, except for amylase, occurred in whole hemolymph as well as in the 4000 g pellet and supernatant. 3. Based on earlier observations, these enzymes are believed to be of cellular origin within hemolymph cells. 4. In the case of amylase, it only occurred in the whole hemolymph and/or serum and is believed to have originated from the crystalline style.

A description is given of an outbreak of equine infectious anaemia (E.I.A.) in Campania [at Naples and Aversa (Caserta)]; it was diagnosed by clinical, pathological and serological examinations (Coggins test). Using the serum of 45 horses with E.I.A. and 11 healthy horses (controls), numerous investigations were carried out on: enzymes, intrinsic coagulation factors, lipids and other substances. The results obtained were very interesting and show that in this disease there are significant increases in many enzymes (LDH, LAP, gamma-GT, CPK, PK and ALD) and copper. Insignificant increases were found in other enzymes (SDH, GLDH, MDH, ICDH, AIP, lysozyme, cholinesterase, GOT and GPT) and also intrinsic coagulation factors, lipid substances (total cholesterol, esterified cholesterol, triglycerides) and glucose. LDH-1-isoenzyme remains unchanged, whilst AcP decreases slightly.

Fibrogenic effects of amorphous quartz dusts are discussed more and more during recent years. In order to study alterations due to amorphous silica (quartz glass VP 203-006) in comparison with crystalline quartz (DQ-12), an inhalation experiment in rats was carried out. Male Wistar rats were separated in two dust exposed groups (n = 35) and one control group (n = 30). The experiment was carried out in inhalation chambers with a slowly rotating animal cage for 12 months, 7 h per day, and 5 days per week. The dust concentration was 10 mg/m3. After 4 and after 8 months of inhalation, 5 animals of each group were sacrificed. After 12 months 15 rats of the dust exposed groups and 10 controls were euthanized. The remaining animals were kept for another 12 months post-inhalation period. Regarding the macroscopical appearance of the lungs, the relative organ weights and the histomorphological reaction pattern, marked dust depending differences are obvious. In the lungs of DQ-12-exposed animals diffuse structural changes occur, including fibrosis and severe reaction of macrophages. Histology of lungs from quartz glass exposed animals reveals only a slight and focally arranged cellular reaction with a few collagenous fibers. However, in both dust exposed groups the mediastinal lymph nodes are extremely enlarged with severe fibroses. Additionally, the following blood parameters were determined: lysozyme, ACE, GOT, GPT, and AP. The most pronounced changes are detectable in lysozyme and GOT after DQ-12 exposure. After quartz glass exposure, the levels of these parameters are similar to the controls. These results show that the amorphous quartz tested in this experiment (quartz-glass VP 203-006) has to be considered as a compound with certain biological effects. The establishing of occupational standards seems to be justified. But, assessing the effects, the different physical and/or chemical properties of various amorphous quartz dusts have to be considered.

The following 10 enzymes were assayed in 187 amniotic fluid and maternal serum samples at 15-42 weeks of gestation: alkaline phosphatase, heat-stable alkaline phosphatase (only in amniotic fluid), acid phosphatase, alanine aminotransferase, aspartate aminotransferase, alpha-amylase, gamma-glutamyltransferase, creatine kinase, lactate dehydrogenase, and lysozyme. The normal reference ranges are reported for amniotic fluid and maternal serum enzymes, together with the abnormal values accompanying neural tube defects and EPH-gestosis. The determination of gamma-glutamyltransferase, heat-stable alkaline phosphatase and creatine kinase was found to be of appreciable diagnostic significance in clinical practice.

Antitoxic effect of lysozyme was shown on a model of experimental acute toxic hepatitis of rats and mice. Administration of lysozyme to the animals in a dose of 5 mg/kg 24 hours before administration of carbon tetrachloride markedly decreased the level of morphological damages in the liver tissue and promoted a decrease in increased levels of alanine aminotransferase in blood serum. Higher levels of lysozyme in blood serum and cells of mouse peritoneal exudate 3 hours after administration of lysozyme were observed. The role of lysozyme as one of the main products secreted by activated macrophages in providing the general and antitoxic resistance of hepatocytes is discussed. Possible use of lysozyme as a hepatoprotective agent is suggested.

Two cases of type C chronic hepatitis with the presence of epitheloid granulomas were reported. Case 1 was a 44-year-old man who presented with a moderate increase in serum ALT and positive anti-HCV. Histological examination of percutaneous liver biopsy specimens showed dense portal inflammation with piecemeal necrosis. Lobular inflammation was present mederately and a large well-organized epitheloid granuloma was found within a liver lobule. Case 2 was a 55-year-old woman, who was presented because of a slight increase in serum ALT and positive anti-HCV. Histologically, liver biopsy specimens showed lymphoid aggregates in the portal area and slight piecemeal necrosis. Moderate steatosis were noted and an epitheloid granuloma was present in the hepatic lobule. Acid-fast stains were negative for both cases and serum ACE and lysozyme were within normal range. These granulomas were composed of epitheloid cells surrounded by lymphocytes. They were not present within the portal tracts, but were found in the hepatic lobule. The incidence of the appearance of epitheloid granuloma in liver biopsy specimens of type C chronic hepatitis was 2 out of 273 cases (0.73%). The role of HCV infection in the genesis of epitheloid granulomatosis is of much interest and should be investigated.

A series of indicators, including serum lysozyme activity, G-banding chromosome aberration (G-banding CA) analysis, sister chromatid exchanges (SCEs), chromosome aberration (CA), T-lymphocyte transformation rate (TcTR), gamma-GT, GPT and AKP, were employed in the present survey among occupationally vinyl chloride (VC) exposed workers and inhabitants living in VC polluted area in a polyvinyl chloride (PVC) factory. The results showed that the serum lysozyme (S-LZM) activities in Group 3 (adult inhabitants exposed to 0.20 mg/m3 VC for at least 8 years), Group 2 (workers exposed to 4.1 mg/m3 for at least 7 years occupationally), Group 1 (workers exposed to 25.7 mg/m3 for at least 2 years) were significantly higher than control. G-banding CA analysis showed that the total chromosome breakage rates in both Groups 1 and 2 were higher, but no difference existed between Group 3 and control. Only Group 1 was observed having higher SCEs, CA level and lower TcTR than control. AKP levels in Groups 1 and 2 were higher than control, but no gamm-GT and GPT differences were found among groups. The study also suggests that G-banding CA analysis is more sensitive than CA and SCEs.

The natural compounds which affect defensive mechanisms of organism are important in prophylaxis and therapy of diseases in human and animals. Lysozyme is an enzyme which originates from chicken egg proteins. It modulates non-specific and humoral immunological mechanisms. A higher bioactivity has a lysozyme dimmer. The aim of study was assessment of influence of the lysozyme dimmer on chosen blood parameters, morphology and functions of internal organs and healing processes of experimental wounds in rabbits. Lysozyme dimmer (KLP-602) was used obtained process polymerisations enzyme lyzosyme from chicken egg white. The experimental group were on New Zealand White rabbits. Systemic reactions were investigated in animals after two injections of lysozyme dimer in dose 0,02 mg/kg b.w. during 21 days. Blood was collected before and after administration of lysozyme dimer in 4, 6, 24 h and in 3, 7, 21 day after first and in 4, 24 h and 3, 7 day after second injection. The following parameters were evaluated of red blood cells number (RBC), hemoglobin concentration (HGB), haematocrit value (HCT), red blood cell indices (MCV, MCH, MCHC), white blood cells number (WBC) and leukogram. Total serum proteins, components C3 and C4 of complement, immunoglobulins G and M, concentration were determined in the serum. Activated partial thromboplastin time (APTT), prothrombin time (PT) and fibrinogen concentration were evaluated in the plasma. Simultaneously, the activity of alkaline phosphatate, GPT and GOT were assessed. Administration rabbits with lysozyme dimmer caused slight decrease in RBC number, Hb concentration, HCT and the neutrophils percentage and increase in the lymphocytes percentage. The concentrations of TSP, immunoglobulins, the components of complement ware increased too. APTT an PT were normal but the fibrinogen concentration was increased. The activity of GOT and GPT were unchanged. Changes are in range of value normal and step out more quickly after two injection than after firste injection. The morphology of organs (liver, lungs, heart and kidneys) was normal.

Sarcoidosis is a granulomatous disease of unknown origin, with pulmonary findings in more than 90% of patients. Extrapulmonary involvement is common and all organs can be involved (especially lymph nodes, eyes, joints, central nervous system) but it is rare to find an isolated extrapulmonary disease (less than 10% of patients). Granulomatous inflammation of the spleen and the liver is common in patients with systemic sarcoidosis, while hepatosplenic enlargement is unusual and splenic involvement rare. We report two cases of systemic sarcoidosis, that onset with splenic and hepatosplenic disease, and one case with splenic sarcoidosis without pulmonary involvement. In the first case a 53-year-old woman with mild abdominal pain underwent sonography and CT, which revealed one hypoechoic/hypodense splenic lesion. Laboratory tests were normal. In order to exclude a lymphoma, splenectomy was performed: histology revealed a sarcoid granuloma. After surgery the patient was asymptomatic and now, after two years, disease is silent. The second case is a 66-year-old woman with a recent weight loss (8 kg in two months) and alterated liver function tests (AST 61 U/l, ALT 72 U/l, Alkaline phosphatase 748 U/l, g-GT 381 U/l). Since she had a familiar history of colon cancer, abdominal US scan, abdominal CT scan and MRI were performed and showed inter-aorto-caval lymphadenopathies and discreet multiple bilobar hepatic and splenic substitutive lesions, with no signs of primary tumor. Upper and lower GI endoscopy, full gynecological workup, complete set of tumor markers, bone marrow biopsy were performed. All resulted negative for neoplasia. Small pulmonary infiltrations were observed on chest-CT scan but cytology on BAL was normal. Infections were also excluded. An exploratory laparotomy showed whitish peritoneal, hepatic and splenic nodules. The histological exam revealed chronic granulomatous lesions typical for sarcoidosis. During a two-year follow-up after the splenectomy the patient feels well without any treatment. The third patient is a 32-year-old woman with mild epigastric pain after meals. Neck-thoracic CT, bone scintigraphy and upper GI endoscopy were negative. Abdominal US and MR showed splenomegaly with multiple splenic lesions. Splenectomy was performed and histological exam showed chronic granulomatous lesions typical for sarcoidosis. Further laboratory tests were normal, except for ACE (66 UI/l). After the surgery ACE became normal and now, three years later, the patient is still asymptomatic. We conclude that hepatosplenic involvement is less rare than it is thought. It is often oligosymptomatic or accompanied with unspecific manifestations and laboratory abnormalities. The diagnosis could be difficult; in fact typical laboratory findings of sarcoidosis such as ACE, lysozyme, calcium, were not diagnostic. Ultrasonography and CT were important but the diagnosis was established only with the histological examination of suspected lesions. This latter required to differentiate liver and/or spleen sarcoidosis from tuberculosis and other infections, primary biliary cirrhosis, metastasis or malignant lymphoma.
