Essential hypertension is considered to be caused by a complicated combination of genetic and environmental factors. Alterations of lipid metabolism in plasma have been reported to be related to an increased risk of essential hypertension. The purpose of this study was to investigate the relationship between two genetic polymorphisms (Pvu II and Hind III RELPs) of the human lipoprotein lipase (LPL) gene and essential hypertension in korean population. In our result the Pvu II RFLP of LPL gene was significantly associated with essential hypertension (P < 0.05). Therefore, we suggest that the Pvu II RFLP of LPL gene may be useful as a genetic marker for essential hypertension in Korean population.

Objectives : To determine the evidence of effectiveness and safety of Chuna manual therapy(CMT) for essential hypertension Methods : We searched 11 electronic databases(Pubmed, Web of Science, EMBASE, Cochrane Library, CAJ, KISTI, KISS, NDSL, KMBASE, RISS, DBpia) and related 2 journals up to April 2017. We included randomized controlled trials(RCTs) of testing Chuna manual therapy for hypertension patients. Results : Twenty one RCTs were eligible in our inclusion criteria. The meta-analysis of eighteen studies showed positive results for the using Chuna manual therapy for essential hypertension. Conclusions : There is favorable evidence of Chuna manual therapy for treating essential hypertension with meta-analysis. However, our systematic review has limited evidence to support Chuna manual therapy for essential hypertension because of low quality of original articles and further well-designed RCTs should be encouraged.

Essential hypertension is a multifactorial disease, and has been shown to be associated with insulin resistance. The relationship between the genetic variation of the insulin receptor (INSR) gene and essential hypertension In Korean population was investigated by the Nsi 1 restriction fragment length polymorphism (RFLP) pattern of this gene. The observed genotype frequencies of INSR gene were not deviated from those expected for the Hardy-Weinberg equilibrium (HWE), but a significant association was observed between essential hypertension and N1 allele of Nsi 1 RFLP at the INSR gene ($X^2$-test; P<0.05). Moreover, the frequency of N1 allele was significantly different between normotensives and essential hypertensives in subgroups that were not obese ($X^2$-test; P<0.05). These data suggest that the Nsil RFLP of INSR gene may be a useful genetic marker for essential hypertension in Korean population.

The etiologic role of renin-angiotensin system and sodium-volume status in the pathophysiology of various forms of hypertension was investigated. Plasma renin activity (PRA) was measured by radioimmunoassay, while sodium-volume status was evaluated by the determination of total exchangeable sodium(NaE) using isotope dilution method. The subjects consisted of 25 controls, 24 patients with essential hypertension, with chronic renal failure (13 with hypertension, 9 without hypertension) and with malignant hypertension. The results were as follows: 1. An inverse correlation between NaE and PRA was noted in control subjects (r=-0.598, p<0.001) and normal renin essential hypertension(r=-0.551, p<0.05) and the chronic renal failure with hypertension. (r=-0.790, p<0.001) 2. NaE increased markedly the in chronic renal failure with hypertension ($66.9{\pm}8.69mEq/kg$ of LBM, p<0.001) and the chronic renal failure without hypertension ($54.9{\pm}9.28mEq/kg$ of LBM, p<0.05), while mild increase was noted in malignant hypertension ($51.7{\pm}6.24mEq/kg$ of LBM, 0.05$50.1{\pm}7.24mEq$) as well as in its renin subgroups.(p>0.1) 3. Absolute value of PRA was not deviated significantly from control group ($2.53{\pm}1.416ng/ml/hr$) except in malignant hypertension ($6.09{\pm}2.042$, p<0.001). But PRA was inappropriately high in relation to prevailing NaE in the chronic renal failure with hypertension (eleven of thirteen patients) and malignant hypertension (ten of fourteen patients), while PRA variatiation was within physiologic range in the chronic renal failure without hypertension. 4. The NaE-PRA product was markedly increased in the chronic renal failure with hypertension ($514.4{\pm}42.10$, p<0.001) and in malignant hypertension ($442.7{\pm}55.03$, p<0.001), while moderately increased NaE-PRA product was noted in the chronic renal failure without hypertension ($402.6{\pm}59.67$, p<0.001). No significant difference in NaE-PRA product was noted in essential hypertension ($354.4{\pm}62.38$, p>0.1). It is suggested that renin-angiotensin system plays a predominant role in the pathogenesis of malignant hypertension and in hypertension of chronic renal failure, though sodium retention is also contributing factor. PRA variation in essential hypertension does not appear to be associated with any consistent change in Na-volume status, suggesting the existence of another mechanism in the genesis of hypertension and PRA variation.

Background: Hypertension is one of the major risk factors for stroke, heart attack, heart failure and kidney failure, thereby causing deaths and disability world-wide. The most predominant type of HTN is essential hypertension (HTN). Unani scholars have mentioned about the clinical manifestations and management of the hypertension and documented it in the context of 'Imtila'. The drug Sankhaholi (Evolvulus alsinoides Linn.) is one of the widely prescribed medicines for the management of essential hypertension in Unani medicine. Material and Methods: The present clinical study was carried out to evaluate the safety of Sankhaholi (Evolvulus alsinoides Linn.) in the management of stage-1 essential hypertension. Newly diagnosed 41 patients of Essential Hypertension (22 patients were in the test group and 19 patients in the control group) were enrolled for the study. All the patients in the test group were given with the test drug 3 g powder of Sankhaholi twice a day for 6 weeks orally. Patients in the control group were given standard drug Ramipril 5 mg once a day for the same duration. Clinical as well as hematological parameters were recorded before and after the treatment. Results: No significant changes are recorded in safety parameters viz. CBC, Haemogram, LFT and KFT. Clinically no adverse effect of the drug has been reported during the course of treatment. Also, significant effect on the systolic blood pressure (p<0.001) were recorded in test group. The drug Sankhaholi was also found effective on the symptoms associated with hypertension. Conclusion: The finding of the study revealed that the test drug Sankhaholi (Evolvulus alsinoides Linn.) is safe and has substantial efficacy as an antihypertensive drug.

Essential hypertension is a heterogeneously multifactorial disease in which blood pressure is harmfully high without overt cause. Both genetic and environmental factors have been implicated in its etiology. In view of the regulatory role of this peptide in the carbohydrate metabolism and renin-angiotensin system, amylin gene has been proposed to a candidate gene for essential hypertension. Therefore, we scanned the amylin gene for mutations in 133 Korean normotensives and 61 essential hypertensives by single-strand conformational polymorphism, and found a single heterozygous S20G missense mutation. However, no significant difference was observed between normotensives and essential hypertensives in the distribution of allele and genotype frequencies of this mutation at the amylin gene (P>0.05). This finding suggests that S20G missense mutation of the amylin gene are unlikely to contribute to the etiology of essential hypertension in the Korean population.

To investigate the effect of ginseng on blood pressure (B.P.) in spontaneously hypertensive rat (SHR) and essential hypertension ginseng extract was given per se daily in 58 SHR and 35 essential hypertensive patients. SHR were divided into 5 groups according to the dosage of ginseng. In essential hypertension 1,000mg of ginseng extract was given. The B.P. in SHR was measured by tail cuff method. In essential hypertension side effect and changes in various laboratory examinations were evaluated. In SHR ginseng appeared to have hypertensive effect when it is given in small amount(10mg/kg). However, when it is given 60mg/kg/day or more difinite B.P. lowering effect was observed. The hypotensive effect was dosedependant and it lasted for 37days of observation. In essential hypertension in 12 $(80\%)$ among 15 patients hypotensive effect was seen with ginseng administration along and the effect lasted for 12 weeks. In the rest of hypertensive patients it is required addition of diuretics of other antihypertensive drugs to decrease B.P., no appreciable side effect was seen. In laboratory examinations no significant changes were seen except for serum cholesterol, ${\alpha}-and\;{\beta}-lipoprotein,$ and hematocrit. There was some evidence of relationship between plasma renin activity (PRA) and ginseng in hypotensive action.

In view of the effect of factor Ⅶ as a risk factor for essential hypertension, we investigated the length (I/D) polymorphism at position 323 promoter region and exon 8-Msp I RFLP of the human factor Ⅶ gene in the Korean patients with essential hypertension and normal controls. There were no significant differences in the allele, genotype and haplotype frequencies of these polymorphisms between normotensive and essential hypertensive subjects. The significant linkage disequilibrium was however, detected between two polymorphic sites. The Msp I RFLP and I/D polymorphism were also significantly associated with plasma triglyceride (TG) levels. Therefore, our results suggest that the significant association between two genetic variations in the human factor Ⅶ gene and plasma TG level may reflect the potential role of human factor Ⅶ gene as one of the genetic components for cardiovascular risk.

Several studies have demonstrated the importance of angiotensin-converting enzyme (ACE) insertion (I)/deletion (D) polymorphisms in the pathogenesis of hypertension. This study sought to determine the association between the ACE I/D polymorphism and essential hypertension in young Pakistanis. The frequency of the ACE I/D polymorphism was established by a comparative cross-sectional survey of Pakistani patients suffering from essential hypertension and ethnically matched normotensive controls. Samples were collected from tertiary care hospitals in northern Pakistan. Hypertensive individuals were defined as those with a systolic blood pressure > 140 mmHg and/or diastolic blood pressure > 90 mmHg on three separate occasions, or those currently receiving one, or more, anti-hypertensive agents. DNA samples obtained from hypertensive (n=211) and normotensive (n=108) individuals were typed by PCR. The frequency of the ACE I/I genotype was significantly higher in hypertensive patients, aged 20-40 years, than in normotensive controls of the same age group ($\chi^2$ = 4.0, P = 0.041). Whereas no overall significant differences were observed between the I/I, I/D and D/D ACE genotypes (One way ANOVA, F=0.672; P=0.413). The association between the ACE I/I genotype and essential hypertension in individuals aged $\leq$ 40 years suggests that ACE has a role in early onset essential hypertension in Pakistan.
