AbstrakSaat ini jumlah perokok, terutama perokok remaja terus bertambah, khususnya di negara-negara berkembang. Keadaan ini merupakan tantangan berat bagi upaya peningkatan derajat kesehatan masyarakat.Setiap kali menghisap asap rokok, apakah sengaja atau tidak, berarti juga mengisap lebih dari 4000 bahan kimia dan 200 diantaranya beracun, diantaranya nikotin, gas CO dan tar.Karbon monoksida (CO) menimbulkan desaturasi hemoglobin, menurunkan langsung persediaan oksigen untuk jaringan seluruh tubuh termasuk miokard. Fakta menyatakan bahwa perokok bernafas pada 250 ml CO dari setiap bungkus rokok. CO mengurangi kemampuan eritrosit untuk membawa oksigen dan tubuh mengkompensasi hal ini dengan memproduksi lebih banyak eritrosit. Dengan demikian, CO meningkatkan viskositas darah, sehingga mempermudah penggumpalan darah.Tujuan dari penelitian ini untuk mengetahui hubungan jumlah dan lamanya merokok dengan viskositas darah. Penelitian ini menggunakan metode studi deskriptif analitik, dengan menggunakan desain penelitian Cross Sectional Study. Penelitian ini terdiri dari 30 orang laki-laki perokok dengan umur berkisar 16-40 tahun. Kadar viskositas darah ditentukan dengan menggunakan alat Viskosimeter Oswald.Data dianalisis dengan menggunakan SPSS dan hasil analisis statistik dinyatakan bermakna bila didapatkan harga p < 0,05.Hasil dari penelitian menunjukkan tidak terdapat peningkatan viskositas darah laki-laki perokok dari viskositas darah normal (viskositas darah normal 3-4 kali viskositas air) rerata 1,64150 cP ± 0,184573 (viskositas air 0,6947cP). Terdapat korelasi positif antara jumlah rokok yang dihisap setiap hari dengan viskositas darah ( r = 0,228 dan p > 0,05). Terdapat korelasi positif antara lamanya merokok dengan viskositas darah (r = 0,318 dan p > 0,05).Hasil dari penelitian ini dapat disimpulkan bahwa terdapat hubungan antara jumlah rokok yang dihisap setiap hari dan lamanya merokok dengan viskositas darah.Kata kunci : Viskositas Darah, PerokokARTIKEL PENELITIAN138AbstractRecently number of smoker, especially young smoker increasingly increase, especially in the developing countries. This condition is heavy challenge to exert incrasing the public health degree.Every smoke, both intentionally or not, it also means suck more 4000 chemical matters and 200 have poison, include nicotine, CO and tar.Carbon monoxide (CO) result hemoglobin desaturation, direct decrease oxygen store for tissue in body included myocard. In fact suggest that the smokers breath on 250 ml CO from a pack of cigarette. CO reduce erythrocyte capability to carry oxygen and the body compensate it with producing more erythrocyte. Thus, CO increase blood viscosity, so that facilitate blood clotting.The aim to this study is to know association of number and duration of smoke with blood viscosity. This study using analytic descriptive study method, with using Cross Sectional Stud design. This study include 30 somker men with 16-40 years ages. The blood viscosity level is defined with Oswald’s viscosimeter.Data is analyzed using SPSS and its statistical analyses result is significant with p <0,05.Result indicate that there are not increasing blood viscosity of smoker men form normal blood viscosity (normal blood viscosity is 3-4 water viscosity) with mean 1,64150 cP ± 0,184573 (water viscosity = 0,6947 cP). There are positive correlation between number of cigarette smoked everyday with blood viscosity (r = 0,228 and p >0,05). There are positive correlation between duration of smoke and blood viscosity (r = 0,318 and p >0,05).The result of this study can be concluded that there are association between number cigarette smoked everyday and duration of smoke with blood viscosity.Key word : Blood viscosity, smoker.

SummaryUsing guinea pigs, a study was conducted on the effects of KBT-3022, a new anti-platelet agent, on hemorheological properties in various tests including blood filterability, blood viscosity, shear stress-induced red blood cell (RBC) deformability and contents of ATP and 2,3-diphosphoglycerate (2,3-DPG). Oral administration of KBT-3022 at 1 and 10 mg/kg significantly increased blood filterability, and significantly reduced blood viscosity at 10 mg/kg without changing the hematocrit, plasma fibrinogen concentration or plasma viscosity. KBT-3022 (10 mg/kg, p.o.) improved RBC deformability in response to shear stress, which was evoked by passing the blood through a thin tube. This dose of KBT-3022 also increased the contents of ATP and 2,3-DPG in RBC. These findings indicate that KBT-3022 may reduce blood viscosity as a sequel to improvement of RBC deformability through direct action on RBC. The increase in the intracellular levels of ATP and 2,3-DPG was considered to be involved in this improvement of hemorheological properties. These hemorheological effects of KBT-3022 appear to be promising for the treatment of patients with ischemic vascular disease.

A series of 40 patients with TIA (25 males and 15 females) was thoroughly investigated by means of angiography and computerized tomography, and divided into a group (A) of 15 “sine materia”, and a group (B) of 25 with direct or indirect evidence of vascular occlusive or stenotic changes. Blood viscosity at 230 sec-1 37° was cp 4.2 ± 0.3 in the controls, cp 4.7 ± 0.7 in all patients (p < 0.05) cp 4.98 ± 0.7 in all male patients (p < 0.01 versus male controls), and cp 4.75 ± 0.8 in group B (p < 0.02). Haematocrit and Fibrinogen were also significantly increased in all male patients and in group B. Circulating platelet aggregates (CPA) were increased in 40% of the patients. Almost all patients with elevated CPA were males, with a slight prevalence in group B. Changes in blood viscosity parameters and in platelet aggregation in TIA patients were therefore related both to evidence of vascular lesions, and to sex, since they were found to prevail in male patients of both groups.

Haemorrheological factors have been shown to be affected in many kings of vascular disease. The present study was undertaken to correlate these factors in normal subjects and patients suffering from peripheral arterial disease. Twenty-two patients were investigated; they had moderate or severe intermittent claudication, extent of disease being confirmed by aorto-arteriography and ankle-systolic pressure studies. Twenty-five controls with no symptoms or signs of arterial disease were selected with comparable age and sex distribution. Whole blood viscosity was measured at shear rates of 230 secs-1 and 23 secs-lat 37°c using a Wells Brookfield cone plate microvisco meter. Plasma viscosity was also measured in an identical manner. Erythrocyte flexibility was measured by centrifuge technique and fibrinogen concentration as well as haematocrit by standard techniques. The fibrinogen concentration appeared to be the only significant parameter; the mean concentration in patients with peripheral vascular disease of 463 ± 73mg/l00ml in the control group ( < 0.05). Although whole blood viscosity was high in patients, when corrected to a common haematocrit, there was no significant difference between patients and controls. The same megative correlation was found for plasma viscosity. The red cell flexibility was found to be increased in patients as compared to the control group, but this effect appeared to be simply proportional to the fibrinogen concentration.

SummaryWe have previously shown abnormalities of haemostasis suggestive of intravascular coagulation in patients with malignant hypertension, a condition associated with retinopathy and renal fibrin deposition. To determine whether such abnormalities are specific to malignant hypertension, we have measured several haemostatic and haemorheological variables in 18 patients with malignant hypertension (Group 1), 18 matched healthy controls (Group 2), and 18 patients with non-malignant hypertension (Group 3) matched for renal pathology, blood pressure and serum creatinine with Group 1. Both Groups 1 and 3 had increased mean levels of fibrinogen, factor VIIIc, beta-thrombo- globulin, plasma viscosity and blood viscosity (corrected for haematocrit); and decreased mean levels of haematocrit, antithrombin III and platelet count. Mean levels of fast antiplasmin and alpha2-macroglobulin were elevated in Group 1 but not in Group 3. We conclude that most blood abnormalities are not specific to malignant hypertension; are also present in patients with non-malignant hypertension who have similar levels of blood pressure and renal damage; and might result from renal damage as well as promoting further renal damage by enhancing fibrin deposition. However increased levels of fibrinolytic inhibitors in malignant hypertension merit further investigation in relation to removal of renal fibrin.
