When adipose tissue enlarges in obesity, as the result of an imbalance between caloric intake and caloric expenditure, many changes occur in the cellular components of the adipose mass. A combination of increased cell size and number underlies the accretion of the adipose mass, however, only a reduction in cell size is possible with weight loss. Several metabolic abnormalities accompany obesity--most important--hyperinsulinemia, hyperlipidemia, insulin resistance, and carbohydrate intolerance. Clinical consequences of obesity include hypertension, venous insufficiency, gallbladder disease, osteoarthritis, pulmonary and cardiovascular insufficiency, diabetes, and atherosclerotic cardiovascular disease, and all are dependent on the severity and duration of the obesity. Once established, obesity is difficult to correct because of the development of many adaptive mechanisms by which obesity defends itself.

The non-healing leg ulcer is examined by discussing three disease processes: peripheral vascular occlusive disease (PVOD), chronic venous insufficiency (CVI), and vasculitis. For PVOD, management decisions are based on risk factors and disease history. Comprehensive management includes the discontinuation of smoking, exercise conditioning and regulation of diabetes, hyperlipidemia, hypertension, and the appropriate application of anticoagulant/antiplatelet drugs. Methods of surgical management include bypass with autogenous or synthetic material in addition to reconstructive surgery with patch angioplasty or extra-anatomic bypass, amputation, percutaneous transluminal angioplasty/stents, thrombolytic infusion, atherectomy, intraluminal ultrasound, and angioscopy. The optimal healing environment for all ulcers prevents contamination, pain, and fluid loss. In CVI, higher venous pressure in the veins of the lower limb during exercise results in ambulatory venous hypertension and ulceration. Various theories are associated with the disease and ulceration process; the classic treatment of elevation, ambulation, and compression for venous disease remains unchallenged. Diagnosis is based on history, physical examination, invasive venography, and/or non-invasive studies. Two groups of vasculitic disorders that share varying degrees of vascular inflammation and necrosis are arteritis (lupus, erythematosus, periarteritis nodosa, dermatomyositis) and blood dyscrasias (sickle cell disease, thalassemia). Leg ulcers associated with vasculitis are due to inadequate tissue oxygenation at the local level, are typically chronic, slow to heal, and commonly recur.

The pretibial area is the most frequently affected site in necrobiosis lipoidica (NL), but proposed mechanisms of NL cannot fully explain this high frequency. Although a few case reports indicate NL patients are complicated with venous insufficiency, no accurate assessment of the relationship between these two conditions has been performed. By using color Doppler ultrasonographic screening of four NL patients for venous insufficiency, we detected venous insufficiency in at least one leg of each patient. NL lesions were observed on all legs with venous insufficiency, and laboratory examination findings revealed that all the patients had hypercholesterolemia. The skin lesions did not respond satisfactorily to 6-month use of anticholesterolemic medication and elastic stockings. However, these results indicate that both hyperlipidemia and venous reflux, in addition to other pathogenic factors, can trigger tissue damage in the lower legs and lead to the onset of NL.

In Western patient populations, the reported incidence of imaging-demonstrated deep vein thrombosis (DVT) after total hip arthroplasty (THA) is as high as 70% without prophylaxis. The reported rates of symptomatic pulmonary embolism (PE) after THA in recent studies range from 0.6% to 1.5%, and the risk of fatal PE ranges from 0.11% to 0.19% in the absence of prophylaxis. Predisposing factors to DVT in western patients include advanced age, previous venous insufficiency, osteoarthritis, obesity, hyperlipidemia, dietary and genetic factors. However, Asian patients who have undergone THA have a strikingly low prevalence of DVT and virtually no postoperative PE. Some authors suggest low clinical prothrombotic risk factors and the absence of some DVT-related genetic factors in Asian patient populations decrease the risk of DVT, PE or both. In Korea, the prevalence of DVT after THA without thromboprophylaxis have ranges from 6.8% to 43.8%, and asymptomatic PE have ranges from 0% to 12.9%; there have been only two reported cases of fatal PE. Deep-wound infections resulting from postoperative hematomas or prolonged wound drainage have been reported with routine thromboprophylaxis. The prevalence of DVT differs varies based on patient ethnicity. Guidelines for the use of thromboprophylaxis were altered and focus on the potential value of outcomes compared with possible complications (e.g., bleeding).

Lamiaceae (Labiatae) are an important group of medicinal plants, which have been used for treating heart disease in traditional medicine for centuries. These mainly aromatic plants are used as essential oils, extracts or isolated components (polyphenols, phenolic compounds, terpenes, iridoids etc.). Some Labiatae species (more than 30, such as cornmint, lavender, patchouli, rosemary etc.) are famous for their use in essential oil production worldwide. In this review, cardioprotective effects of Lamiaceae and their active secondary metabolites, as well as mechanism of action against cardiovascular diseases (hypertension, angina pectoris, hyperlipidemia, thromboembolism, coronary heart disease, heart failure, venous insufficiency, arrhythmia) will be discussed. Use of Labiatae as food or food additives (such as spices) may prevent risk of cardiovascular diseases, diabetes and cancer. This approach is also described as a part of the article. Studies on developing new, effective and safe natural products from Lamiaceae (rich source of flavonoids and other active compounds) are promising and may offer prevention and treatment for patients with coronary disease and other related diseases.
