Code mixing can be happened in wide variety of language. It means that, mixing of two or morelanguages can be happened in morpheme/word, phrase, clause, and in sentence. According to Hamers(2000:270) “Code mixing is a language-contact communication strategy, but the speaker of a languagetransfers elements or rules of another language.”The researcher taught that English is important language,The reason to choose code mixing because the researcher found that students try to practice their Englishbut using sometime they have to use code mixing and swithing mostly because of lack of vocabulary.To describe the types of code mixing, to explain the functions of code mixing, and to tell the reasons ofusing code mixing. According to Siregar (1996:50) stated that Code mixing divided into two kinds, intrasentential mixing and extra-sentential mixing.Muysken (2000) defined three types of code mixing, thoseare: Insertion, Alternation, and Congruent Lexicalization.This situation is closer with daily conversationand also describe as their habitual communication. Speech situation of some people this phenomenoncould increase by status in society. In this case, for many young people code mixing becomes their ownstyle which is hoped to look like a modern and educational one.

Twenty patients with mild to severe essential hypertension completed a 12-week open crossover study to compare the effectiveness and tolerance of two beta-blocker/diuretic combinations. Patients were allocated at random to receive treatment for 6 weeks with either 40 mg propranolol plus 12.5 mg hydrochlorothiazide twice daily or 400 mg acebutolol plus 25 mg hydrochlorothiazide once daily. They were then crossed over to the alternative medication for a further 6 weeks. Blood pressures and pulse rate were monitored in the supine and erect positions at regular intervals, as were side-effects, laboratory variables and ECG. The results showed that both combinations produced significant reductions from baseline in systolic and diastolic blood pressures but that the acebutolol combination produced a significantly greater reduction in diastolic blood pressure. There was no evidence of a treatment sequence effect. The two drug treatments were reasonably well tolerated, with a trend in favour of the acebutolol combination. No clinically significant changes were observed in any of the laboratory parameters investigated and there were no ECG abnormalities.
